little progress = still looking for usb devices

hey there. i am running Arch w/ 2..6.7

my usb system seems to be jaxed up. xcdroast did not find my usb cd/writer and although gtkam selects the right camera for my usb camera, it gives me an error like
"cannot list folders in / " -

i may have some kernel modules that still need to load but i dont know which ones.

any help here would be great. How do you get usb working in Arch ? thanks all

Re: little progress = still looking for usb devices

The impossible missions are the only ones which succeed.

Re: little progress = still looking for usb devices

What kind of usb camera do you have (is it webcam or digital camera)? Since you want to use gtkam I assume that you have digital camera.

The best option for digital cameras is to use hotplug. Search the forums - there was a discussion about it some time ago. There is also an excellent howto in archlinux wiki http://wiki.archlinux.org/index.php/Digital%20Cameras (if you have a webcam there is also howto for it). BTW gtkam is a gui for gphoto2 so check this manual too http://gphoto.sourceforge.net/doc/manual/.
I use canon ixus v3 with digikam and digikam plugins and it works great in arch (forget about gtkam :-))

You should post more info about your hardware especially usb (what version do you have 1.1 or 2.0?, does it work with other distros/systems?). Post the output of lsusb and lspci (you will need to install usbutils and pciutils if you don't have them already). Almost all of my usb stuff works in arch except my usb webcam (samsung mpc-c30 philips compatibile - pws module) but this is because the driver is too buggy and it has a lot of problems with devfs - not a big deal since I don't really need it :-). I also had some troubles with my wacom usb tablet setting but this is another problem connected with kernel mouse drivers.

I don't know anything about using usb writers in linux but if you post your hardware info I'm sure we can find something with google.

Re: little progress = still looking for usb devices

ok, well i got the usb camera working. Google prodced this, modprobe ochi-hcd. so i did that and added it to rc.conf and now the camera works ok. still think i am going to go for digikam though. he he.

the CDRW is a TDK usb one. Its usb 2 but i think that my motherboard usb port is only usb 1.
It works fine in Debian ( which i got rid of for Arch ) and thats cool. This is the last piece of hardware now i have yet to get going.

the google results also suggested loading echi-hcd but when i tried the messsage i got was "could not find module echi_hcd.

Here is the output from lsusb

Re: little progress = still looking for usb devices

If your motherboard port is only usb 1.1 then you don't need to use ehci-hcd. (By the sound of it it's not available to you anyway). If ohci-hcd is not working for your cdrw then try uhci-hcd - it depends on what type of host controller your motherboard supports.

Re: little progress = still looking for usb devices

I don't have much time now and lsusb/lspci output is not very helpful this time. But you can try this google query: http://www.google.pl/search?q=%28k3b+OR … gle+Search Anything useful?

BTW it's not echi-hcd but ehci-hcd :-)

Re: little progress = still looking for usb devices

Hey there, and thanks for all your help. I found at least one problem somewhere between the keyboard and the chair. he he.
i switched usb ports between camera and CDRW and now xcdroast found the cdrw, but it said to check out how to enable scsi-emulation for it to work right. Why would i need scsi for a usb cdrw ? ok, so i had a connection problem and thats all cool now. i may have a faulty usb port.
Thanks for all of your help and patience.

Re: little progress = still looking for usb devices

scsi emulation is deprecated in 2.6 kernels - there are other threads on this forum about cd writing...this one should be helpful
