Comment 20 for bug 341827

I have a similar problem with a USB connected HP PhotoSmart 257x, where the /var/log/messages file quickly is filled with

Jul 29 19:37:07 localhost Photosmart_2570_series?serial=MY6A4311RT04DY: io/hpmud/musb.c 725: invalid deviceid wIndex=1, retrying wIndex=100: Device or resource busy

I don't know exactly what triggers this, as the printer is apparently working fine both when printing and when scanning.

Installed versions:

hplip-2.8.12-6.fc10.i386
cups-1.3.10-5.fc10.i386
