I''m trying to get a USB camera working, however it, nor any of my other USB devices, are showing up in usbview. I''ve tried all sorts of devices that used to work, but all give the same non-working results. I tried loading the usb-storage module, but that made no difference. Here is the output of dmesg when I try to connect the camera. ehci-hub.c: GetStatus port 1 status 0x3012 OWNER POWER speed=0 OC CSC hub.c: port 1, portstatus 0, change 1, 12 Mb/s hub.c: port 1 connection change hub.c: port 1, portstatus 0, change 1, 12 Mb/s ehci-hub.c: GetStatus port 2 status 0x1c13 POWER speed=3 OC CSC CONNECT hub.c: port 2, portstatus 509, change 1, 480 Mb/s hub.c: port 2 connection change hub.c: port 2, portstatus 509, change 1, 480 Mb/s hub.c: port 2, portstatus 509, change 0, 480 Mb/s hub.c: port 2, portstatus 509, change 0, 480 Mb/s hub.c: port 2, portstatus 509, change 0, 480 Mb/s hub.c: port 2, portstatus 509, change 0, 480 Mb/s hub.c: port 2, portstatus 519, change 0, 480 Mb/s hub.c: port 2 of hub 1 not reset yet, waiting 10ms hub.c: port 2, portstatus 519, change 0, 480 Mb/s hub.c: port 2 of hub 1 not reset yet, waiting 10ms hub.c: port 2, portstatus 519, change 0, 480 Mb/s hub.c: port 2 of hub 1 not reset yet, waiting 200ms ehci-hub.c: 00:1d.7 port 2 full speed, give to companion, 0x1c11 ehci-hub.c: GetStatus port 2 status 0x3c11 OWNER POWER speed=3 OC CONNECT hub.c: port 2, portstatus 0, change 10, 12 Mb/s ehci-hcd.c: 00:1d.7: free_config devnum 0 ehci-hub.c: GetStatus port 3 status 0x3012 OWNER POWER speed=0 OC CSC hub.c: port 3, portstatus 0, change 1, 12 Mb/s hub.c: port 3 connection change hub.c: port 3, portstatus 0, change 1, 12 Mb/s ehci-hub.c: GetStatus port 4 status 0x3012 OWNER POWER speed=0 OC CSC hub.c: port 4, portstatus 0, change 1, 12 Mb/s hub.c: port 4 connection change hub.c: port 4, portstatus 0, change 1, 12 Mb/s ehci-hub.c: GetStatus port 5 status 0x3012 OWNER POWER speed=0 OC CSC hub.c: port 5, portstatus 0, change 1, 12 Mb/s hub.c: port 5 connection change hub.c: port 5, portstatus 0, change 1, 12 Mb/s ehci-hub.c: GetStatus port 6 status 0x3012 OWNER POWER speed=0 OC CSC hub.c: port 6, portstatus 0, change 1, 12 Mb/s hub.c: port 6 connection change hub.c: port 6, portstatus 0, change 1, 12 Mb/s Here is the output of lsmod Module Size Used by Tainted: P usb-uhci 23568 0 (unused) ehci-hcd 21292 0 (unused) floppy 50748 0 (autoclean) nvidia 1626496 20 (autoclean) usbcore 69900 1 [usb-uhci ehci-hcd] cmpci 26392 0 soundcore 3972 2 [cmpci] tulip 42272 2 ppp_synctty 6336 0 (unused) ppp_async 7744 1 ppp_generic 16420 3 [ppp_synctty ppp_async] slhc 5264 0 [ppp_generic]

kernel version?

It''s just a wild guess, but maybe you could use the usb-storage module to download the pictures from your dig. camera. do a ''modprobe usb-storage'' and watch the logs (/var/log/messages iirc) for new entries about usb. There is a chance that your usb camera will function as an emulated scsi device that you can mount and get your pictures from.
Is that what you want to do or am I missing the point?

I''m using kernel 2.4.20.

The usb-storage module doesn''t help, or change things at all. No devices, not just storage are recognized. My tablet isn''t, none of my camera''s are, my USB Drive isn''t, nothing.

Here is something I just found in my logs, searching doesn''t turn up much.

define recognized.

lsusb shows nothing connected when there is stuff connected?

you''re supposed to interface to cameras via userspace tools like gphoto2, btw.

Dude...I''m not a newbie. I''ve been using linux for 5 years now, I just never really used USB much, and it''s always "just worked" before now.

When I type lsusb just the hubs show up, not the connected devices.
When I say recognized I mean that the computer actually shows that there is a device connected. Right now when I connect a device the logs show a status change and that something was powered on, but it never registers a device. I was able to connect my camera to my laptop running Red Hat just fine, it didn''t have a driver to match my camera but it did show up int usbview.

My laptop is using usc-ochi, and my desktop is using usb-uchi. I don''t know if that matters but when I try to load usb-ochi I get errors. I don''t know if that means anything, USB isn''t really my hat.

I didn't imply you were a newbie.

but you still show a slight misunderstanding. The kernel almost never knows WHAT you plug in, only that it IS plugged in. There are not many kernelspace USB drivers, so the only thing I have that the kernel ever recognizes is my printer. Thus, "not recognized" _could_ be answered by saying "so? it shouldn't be."

stuff not showing up in lsusb, on the other hand, is interesting, and is what you need to say explicitly what you say its "not recognized."

after spewing that, I can say: I don't know. If it doesn't show up in lsusb when you connect something, then there's a problem. Ask on linux-kernel, maybe?

edit: Just noticed that you mentioned 'usbview', apologies. I didn't notice because I've never heard of this program.

usbview is like lsusb, only it''s slower and displays with an X window.
