I have a problem with a Deltaco TB-229 keyboard in Linux Mint. When I boot the computer, the keyboard is not recognized until I unplug it, then plug it back in (does not matter if I use the same or a different port). Then it works immediately.
If I restart the computer, then the keyboard is still recognized. So, the problem only appears in case of a "cold" boot.
How can I make sure that the keyboard is recognized right away? I have googled but newcomer as I am to Linux I am still at a loss as to exactly what to do.
I've narrowed it down and this the information for my keyboard (output of
- Code: Select all
lsusb -t
/: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ohci_hcd/10p, 12M
|__ Port 2: Dev 2, If 0, Class=HID, Driver=usbhid, 1.5M
|__ Port 2: Dev 2, If 1, Class=HID, Driver=usbhid, 1.5M
With the verbose option, I get this information:
