Red Hat Bugzilla – Bug 101642
USB printer device names keep changing
Last modified: 2007-03-27 00:08:41 EDT
hDescription of problem:
Disconnecting and reconnecting a USB printer leads to the printer's device
assignment changing from usblp0 to usblp1. Repeating this causes the assignment
to swap back and forth between usblp0 and usblp1. Since CUPS has been
configured to use usblp0, the printer stops working if it's powered off and back
on again and requires a second power cycling to correct the device name.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug USB printer in, switch it on.
2. Unplug printer.
3. Plug printer back in. Note new device assignment in syslog.
Printer gets assigned usblp1 on reconnection.
Printer should stay as usblp0.
This sounds like an issue with the kernel drivers not properly reusing the device.
It's also the fault of redhat-config-printer that this matters at all. :-/
