[sane-devel] Getting HP ScanJet 5300C to work

[Simon J. Rowe]

I am unable to get my elderly ScanJet 5300C working. I've used it 
successfully in the past on Linux and it still works fine on WinXP.

My distro contains sane-backends-1.0.25-5.mga6

It is detected by the kernel

[ 9415.838484] usb 3-1: new full-speed USB device number 5 using uhci_hcd
[ 9416.105505] usb 3-1: New USB device found, idVendor=03f0, idProduct=0701

[ 9416.105514] usb 3-1: SerialNumber: TW07M23383VE

and by scanimage -L

[srowe at nimloth ~]$ scanimage -L
device `v4l:/dev/video0' is a Noname Live! Cam Sync HD VF0770: Live!

device `avision:libusb:003:005' is a Hewlett-Packard ScanJet 5300C 
flatbed scanner

but it hangs while trying to calibrate

Once it's failed the device cannot be detected until it is unplugged and 
plugged back in.

Any ideas how I can debug what's going on?

Thanks
