Hi,
I am trying to get my Microtek Scanmaker 5600 working
with linux. I am using kernel 2.6.8.1 and CVS version
of javax.usb.
Everything seems ok till I submit the scan request.
Here is the relevant section of the UsbSnoopy logs:
63540 ms] >>> URB 323 going down >>>

This is followed by a bunch of more 00s. In the logs,
this is followed by a bunch of data. I am able to get
the scacnner motor to move but all my attempts tot
read the bulk data have failed. I claim the correct
interface, open the correct pipe etc. I have tried
opening the pipe for endpoint 0x81 and syncsubmit an
IRP with buffers of various lengths in different ways
- using a separate thread, or after sending the c0 26
00 00 request etc., but no matter what I send, I get
the Invalid IRP message back.
How is it that I am supposed to read the bulk data
back from my scanner? The scanner has 2 IN endpoints.
I feel very frustrated. Any help would be appreciated.
I have already looked the apis for jsyncmanager, cm19
etc., and tried the way they do it, but nothing has
worked so far.
