#Lsusb doesnt work Pc
I also tried to connect an USB flash stick tha has a led: if I insert it in a PC port, it starts blinking, but if I intert it in a port of the monitor hub, it doesn't turn on the led light at all. There isn't any new device as we had expected. No line has been added to the log file after plugging in the cable. In this way, whe I plug the usb cable It should warn me about the new device. I've also checked the log file /var/log/messages using tailf (it just keeps the log file opened and shows any line added by the system events). The monitor is on (otherwise I couldn't read nothing on the screen :) ). Now the system is up again and lsusb reports the same output as above: no usb device is plugged in. cheers, Danny-To unsubscribe from this list: send the line 'unsubscribe linux-usb' in.

Here some result for test by watch -n 1 lsusb -t". No matter what I do cant get my drives working at USB3 speeds. All ports are free, I use only ssh terminal. Hello, PhilE, thanks for your responsiveness. "watch -n 1 lsusb -t" is a nice, interactive way to see devices being attached and removed. a mouse), testing all four ports to see if there is one that doesn't work. * Bus 2, port 2 - USB3 device in lower USB3 (blue) portĭo you have anything attached to the USB ports during booting? Try using just a single device (e.g. * Bus 2, port 1 - USB3 device in upper USB3 (blue) port * Bus 1, port 4 - USB1/2 device in lower USB2 (black) port * Bus 1, port 3 - USB1/2 device in upper USB2 (black) port * Bus 1, port 2 - USB1/2 device in lower USB3 (blue) port * Bus 1, port 1 - USB1/2 device in upper USB3 (blue) port The blue USB ports are USB3-capable, while the black ports only go up to USB2.
