Description

Technical Field

[0001] This invention relates to USB devices. Specifically, it relates to a high-speed, standard 8-port USB device with a standard optical drive bay. Background Technology

[0002] Currently, most USB interface devices on the market use PCI-e interface adapter cards. A single card supports two USB ports, or multiple USB ports can be expanded by connecting them in series using a hub. This design can only maintain efficient and high-speed data transmission when using two ports. When multiple USB ports are transmitting data simultaneously, due to cost considerations and typical usage scenarios, the hub-and-spoke design will result in a significant decrease in the USB port transmission rate, and the speed of each port will not meet the USB 3.2 Gen 2 standard. Summary of the Invention

[0003] To address the shortcomings of existing technologies where simultaneous data transfer across multiple USB ports, due to cost considerations and typical usage scenarios, often results in a significant decrease in USB port transmission speeds and a failure of each port's speed to meet the USB 3.2 Gen 2 standard, this invention provides a high-speed standard optical drive bay 8-port USB device.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention discloses a high-speed standard optical drive bay 8-port USB device, comprising four sets of parallel-connected dual-port USB adapter boards; each dual-port USB adapter board is a USB 3.2 gen2 adapter board; and each set of dual-port USB adapter boards has two USB output ports; each set of dual-port USB adapter boards is provided with an external power supply pin and an SFF-8643 port; it also includes a PCI-E bus expansion card, and each set of dual-port USB adapter boards is connected to the PCI-E bus expansion card via the SFF-8643 port; it also includes a protective housing designed in the standard optical drive size; the dual-port USB adapter boards and the PCI-E bus expansion card are all installed inside the protective housing, and the protective housing is provided with port slots corresponding to the USB output ports.

[0005] As a preferred embodiment of the present invention, the protective shell has a front width of 148mm, a rear width of 146mm, a length of 150mm, and a height of 42mm.

[0006] As a preferred embodiment of the present invention, the USB output port is a USB type-A port.

[0007] As a preferred embodiment of the present invention, the PCI-E bus expansion card is model LRNV9347L-4I.

[0008] As a preferred embodiment of the present invention, the dual-port USB adapter board is equipped with an ASM3142 USB control chip for controlling the USB output port.

[0009] As a preferred embodiment of the present invention, a connecting plate is used to connect and fix each set of two dual-port USB adapter boards.

[0010] The beneficial effects of this invention are: 1. This high-speed standard optical drive bay 8-port USB device uses four sets of parallel dual-port USB adapter boards, supporting simultaneous data extraction and analysis from eight USB output ports. Each set of dual-port USB adapter boards connects to a PCI-E bus expansion card via an SFF-8643 port, enabling all eight USB output ports to operate simultaneously while maintaining a high speed for each port. The protective housing features a standard optical drive bay design, ensuring compatibility with electronic forensics tables in electronic forensics laboratories.

[0011] 2. The dual-port USB adapter board in this high-speed standard optical drive bay 8-port USB device uses the ASM3142 USB controller chip. Compared with the traditional ASM 2142 USB controller chip, it significantly improves data transmission speed with extremely high energy efficiency and reduces power consumption by 50%. It enables four ASM3142 USB controller chips to work simultaneously and independently in terms of bandwidth. The increase in the number of connected USB storage devices has little impact on the read speed. When eight USB storage devices are connected at the same time for analysis, its maximum speed still maintains a high level. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1 , Figure 2 and Figure 3As shown, this invention discloses a high-speed standard optical drive bay 8-port USB device, comprising four sets of parallel-connected dual-port USB adapter boards 1; each dual-port USB adapter board 1 is a USB 3.2 gen2 adapter board; and each set of dual-port USB adapter boards 1 has two USB output ports 2; each set of dual-port USB adapter boards 1 is provided with an external power supply pin 3 and an SFF-8643 port 4; it also includes a PCI-E bus expansion card 5, and each set of dual-port USB adapter boards 1 is connected to the PCI-E bus expansion card 5 via the SFF-8643 port; it also includes a protective housing 7 designed with standard optical drive dimensions; the dual-port USB adapter boards 1 and the PCI-E bus expansion card 5 are all installed inside the protective housing 7, and the protective housing 7 is provided with port slots corresponding to the USB output ports. The system employs four parallel dual-port USB adapter boards 1, supporting simultaneous data extraction and analysis from eight USB output ports 2. Each dual-port USB adapter board 1 is connected to a PCI-E bus expansion card 55 via an SFF-8643 port 4, enabling all eight USB output ports 2 to operate simultaneously while maintaining a high speed for each port. The protective housing 7 features a standard optical drive bay design, ensuring compatibility with electronic forensics tables in electronic forensics laboratories.

[0017] The protective housing 7 has a front width of 148mm, a rear width of 146mm, a length of 150mm, and a height of 42mm. The protective housing 7 adopts a standard optical drive bay design, making it compatible with electronic forensics tables in electronic forensics laboratories.

[0018] The USB output port 2 is a USB Type-A port. The PCI-E bus expansion card is model LRNV9347L-4I.

[0019] The dual-port USB adapter board 1 is equipped with an ASM3142 USB control chip to control the USB output port 2. Compared to the traditional ASM 2142 USB control chip, the dual-port USB adapter board 1, using the ASM3142 USB control chip, significantly improves data transmission speed with extremely high energy efficiency and reduces power consumption by 50%. It allows four ASM3142 USB control chips to operate simultaneously and independently, minimizing the impact of increased USB storage devices on read speed. Even when eight USB storage devices are connected simultaneously for analysis, its maximum speed remains at a high level.

[0020] Each pair of dual-port USB adapter boards 1 is connected and fixed by a connecting plate 8.

[0021] The internal design of this invention consists of four sets of dual-port USB 3.2 gen2 adapter boards connected together, such as... Figure 4 , Figure 5 As shown, every two sets of adapter plates are connected and fixed using four copper pillars, as per the attached diagram. Figure 6 As shown. Each USB 3.2 gen2 adapter board has two USB Type-A port outputs, as shown. Figure 7 As shown, there are a total of 8 USB ports for connecting external USB storage media.

[0022] Each USB 3.2 gen2 adapter board has one 4-pin external power connector and one SFF-8643 port, as shown in the attached image. Figure 4 The SFF8643 port connects to a PCI-E bus expansion card (model LRNV9347L-4I), enabling eight USB 3.2 ports to operate simultaneously, ensuring each port's speed never falls below 5Gbps. The 4-pin external power supply uses a dedicated 12V supply, which is stepped down to 5.1V to power the USB ports. Each port can draw over 2A, supporting power for all portable hard drives and portable SSDs with power exceeding the USB 3.2 Gen 2 rated power. Even with a 1-meter-long data cable, there will be no power shortage.

[0023] The dual-port USB adapter board designed internally in this invention uses the ASM3142 USB 3.2 control chip, such as... Figure 8 As shown, compared to the traditional ASM 2142 USB controller chip, it significantly improves data transfer speed with extremely high energy efficiency, reduces power consumption by 50%, and through the parallel connection of four dual-port USB adapter boards, enables four ASM3142 USB 3.2 controller chips to operate simultaneously and independently, with a bandwidth of 10Gbps in full-duplex mode. Furthermore, as... Figure 9 As shown, the power supply section of each USB port is designed with electronic fuse protection. If a short circuit fault occurs in the connected USB storage medium, the electronic fuse will automatically disconnect the power supply. The signal circuit section of each USB port is designed with common mode inductor protection circuit to prevent static damage. While protecting the device, it can also prevent the fault of the USB storage medium from escalating.

[0024] The external power supply uses a 12V independent power supply, which is stepped down to 5.1V to power the USB ports. The current of each interface can reach more than 2A, which supports powering all portable mechanical hard drives and portable SSDs and other storage media with power greater than the rated power of USB 3.2 GEN2. Even if the data cable is as long as 1 meter, there will still be no problem with insufficient power supply.

[0025] Each USB port's power supply section is designed with electronic fuse protection. If a short circuit fault occurs in the connected USB storage medium, the electronic fuse will automatically disconnect the power supply. The signal circuit section of each USB port is designed with a common-mode inductor protection circuit to prevent static damage. While protecting the device, it can also prevent the fault of the USB storage medium from escalating.

[0026] Working principle: Four sets of parallel-connected dual-port USB adapter boards 1 support simultaneous data extraction and analysis from eight USB output ports 2. Each set of dual-port USB adapter boards 1 is connected to a PCI-E bus expansion card 55 via an SFF-8643 port 4. This allows all eight USB output ports 2 to operate simultaneously, ensuring that each port maintains a high speed. The protective housing 7 adopts a standard optical drive bay design, making it compatible with electronic forensics tables in electronic forensics laboratories.

[0027] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
