hp scanjet 3300c and libusb errors on opensuse 11.2

English Hardware

I’ve been using this scanner on various suse builds all the way back to version 8. This week I installed OpenSuse on a brand new computer and when I run xsane, I receive these messages.

The scanner will scan for a few seconds and then the entire system freezes up. Any assistance is greatly appreciated.

I fixed this problem but found another problem and will open a thread for it. The solution to this problem was discovered by using the command lsusb to list hte usb devices and determine which bus they were on. After doing that I determined that the scanner device was owned by user root and group lp. I added myself to the lp group and that seemed to help somewhat. Will open a thread for the bigger issue though.

Regards,
Brad

OK. So its not resolved but I’ve opened a thread with more details here:
OpenSuse 11.2 - System locks up when using USB mouse - openSUSE Forums

hoping someone can help. Would hate to have to change distros after so many years of being a happy suse penguin.
