Can you kindly go through the following checklist:
1.
Code: Select all
# lspci -i /usr/share/pci-usb-pcmcia.ids | grep -i "usb"
2.
Code: Select all
# lsmod | grep --extended-regexp "usb|hcd"
3.
Code: Select all
# cat /proc/bus/usb/devices | grep -i --extended-regexp "mouse|keyboard"
4.
Code: Select all
# probepart
If step 1 fails, likely the following will also. Ditto for step 2.
