[sane-devel] OS/2 device driver for HP7450C

[Rene Rebe]

Hi.

The Scanjet 7450 is a normal 7400 and also identifies as such.

If you connect is via SCSI to your OS/2 box it "should" work
out-of-the-box. 

But using USB is not that easy - I guess writing a kernel driver for
OS/2 is not that easy (we would need s.th. like the hpusbscsi) - maybe
I should "convert" my driver to do the scsi-emulation in user-space?
Via libusb or so?

Any hints (I never did any low-level usb prgramming - the hpusbscsi
luckily just appeared ;-)
