Hi
I'm running 12.04 and use an HP 3070 printer/scanner connected by USB.
If I boot with the device already connected and powered up, my scanner software
always detects the device but returns an I/O error when I try to perform a
document scan.
If I boot with the device powered up but NOT connected, then subsequently plug
in the USB cable, everything works fine.
If I get the I/O error, unplugging the USB cable then plugging it back in does
not solve the problem. I have to logout + logon.
I've used Simple Scan, HPLIP and gscan2pdf - it makes no difference.
The printer function works correctly under all connection scenarios.
Something about introducing a new USB device with Ubuntu already running seems
to make all the difference. It's hardly a showstopper but it's still annoying.
Any ideas?
Thanks
Nige
