Bug Description
Binary package hint: cups
the cable (prolific technology pl2305 was attached to the computer and detected using lsusb. after printing a testpage the printer was detached due to space problems. since that moment the cable (and thus the printer) is not seen anymore.
hint: dmesg gives:
new full speed USB device using uhci_hcd and address 40
usb 6-2: device not accepting address 40, error -71
what can I do in order to use the cable again?
thankyou!
p.s.: the same problem occurs when the cable (+ printer) is attached to a notebook (also ubuntu 10.10): no entry at lsusb.

Marking as duplicate of bug #564917. There and in the other duplicates the problem is caused by a USB-to-Parallel adapter but also Prolific Technology PL2305 in most cases. Please try the fix proposed there by booting from a live CD of Natty (and doing all updates after the boot). Does this solve the problem?
Also check whether the "usblp" Kernel module is loaded on your system, by running the command
lsmod | grep usblp
in a terminal window. Try blacklisting the module in
/etc/modprobe. d/blacklist. conf
unload the module via
rmmod usblp
then remove and recreate your print queue.
If the mdule is already blacklisted, try reactivating it by removing the blacklist entry, then removing and recreating your print queue.
Follow also the instructions under "USB printer" on https:/ /wiki.ubuntu. com/DebuggingPr intingProblems.
