I have been attempting to get my CU-SeeMe CamKit Camera to work under
linux. I compiled the modules successfully, and got the modules to load.
On one machine, the system loaded the drivers, but when I attempted to
grab pictures, it was garbled. On the system I am currently trying it on,
the client programs insist the device does not exist. The driver says 1
camera was found, but spits out all sorts of strange information that, at
this point, does not make sense to me. I would appreciate it if someone
on this list could assist me. I apologize if the contents of this message
were contained elsewhere in the mail archives.
In the initial computer setup, I have the parallel port set at ECCEPP1.9,
and I have tried ECCEPP1.7, and I have tried both ECP and EPP. ECCEPP1.9
seems to be the only one that gives me any good results.
Also -- *** I compiled without the DMA option when compiling the modules
to avoid problems. In either case, the setup is not working. ***
This is what I get out of 'dmesg':
