testusb 源码包含在 linux 内核当中, 路径为 linux-5.10\tools\usb\testusb.c 。可以通过 luban 编译,或者简单编译: gcc-Wall-g-lpthread-otestusbtestusb.c 就可以启动测试了: $ sudo ./testusb -a unknown speed /dev/bus/usb/001/002 ...
I would like to validate if the super speed design is correct or not. When plugging into a computer, it seems that the device is recognized as USB 2.0. I have now a strong doubt if I have inverted the RX and TX lanes (the datasheet is very confusing): When I ru...

But it cannot be connected to a usb 2.0 port since that would then bottleneck the connection speed and consequently lower the data transfer rates. Test with Sysbench So finally we can run tests on the disk drive using sysbench. Open a terminal and navigate to the directory where you would ...
