Most likely this is a problem either with the adapter itself or with a
USB hub inbetween. Check the kernel log with
# dmesg | grep -i usb
if there are any USB errors.

I would try to reload the uhci_hcd or ohci_hcd module. If the hardware
supports USB2.0, this should be enclosed into reloading the ehci_hcd module.
# rmmod uhci_hcd ehci_hcd ; modprobe ehci_hcd ; modprobe uhci_hcd
(or ohci_hcd if your system uses this instead of uhci_hcd)
If the USB errors are related to overcurrent, you can try disabling the
overcurrent detection with the ignore_oc module option. Overcurrent
detection sometimes fails because the firmware of host controllers and
hubs is crappy.
Kind regards
