USB Direct-Access / Camera




Thanks to all who replied before to this thread........

Synopsis:  Attempting to connect Fuji FinePix-3800 camera as a mountable external usb drive.  Still not working, but believe I'm closer to the problem.......


More:  I've seen the advice about mounting USB devices, memory, scsi, whatnot and believe that I'm doing all of that part of the mounting correctly.  I've attempted all various mount variations and have not successfully been able to read from the device, even when it's by itself on the scsi list.

I've implemented the suggestion to have my CDROM comfortably working on the non-scsi channel ( I do not see any registered scsi devices in /proc/scsi/scsi until I attempt to mount the usb camera.  This seems alright to me, because I don't know of any advantages in having it run through scsi also...(correct me if you know better).


Curious:    After attempting to connect the USB camera, do get a new scsi device appear in the /proc/scsi/scsi.  The camera get's identified and I'm able to run sniffer stuff like usbtree and see the appropriate stuff show up.  Here's what it looks like....

[danny Jughead danny]$ cat /proc/scsi/scsi

Here's what the relevant part of  /proc/bus/usb/devices file looks like........

Here's where the curious part really starts.........this is my /var/log/messages.......

Those "usb-uhci.c: interupt..." messages keep going until I shutdown....camera on or not.....once attempted (not even to mount, just power up device and connect), they keep going..........to me, it looks like my problem is not so much "mounting the usb as scsi" as it is with the USB.  Bridge?...Internal Hub? Need driver?....I'm at a total loss.....


I really appreciate everyone's help, I've learned a ton up to this point and I'm really trying to "do for myself"....problem is, I don't know what else to read or try......anyone know what the usb-uhci.c file is related to?
