USB Mounting Problems [SOLVED]

Vlad_Paler · 2006-04-23 00:49:14

I've been working with arch for about 4 months now, and there's one problem I just can't solve. I cannot connect any USB devices. I've posed this question on another tech forum, and no one could figure it out there, so I'm hoping someone here can give me a hand.

My computer can see the devices connecting...

usb 1-1: new full speed USB device using ohci_hcd and address 2
usb 1-1: configuration #1 chosen from 1 choice

and my fstab is configured the way it should be

/dev/sda /mnt/usb vfat rw,user,noauto 0 0

but when I try to mount it...

mount /dev/sda
mount: special device /dev/sda does not exist

it's disturbing, but hwd -s used to say

USB : Acer Laboratories Inc. [ALi]|M5237 (USB) module: ohci_hcd

but now... it says

USB : No USB

I'm thoroughly befuddled. Any ideas anyone?

mount /dev/sda

Err, shouldn't you be mounting /dev/sda1, or some formatted partition on it? Or does it not necessarily work that way with USB devices?

(That said, I don't think that the message you get is the right one for that situation... :shock:)

but now... it says
USB : No USB

Umm, what does 'lsmod' say? Does it show ohci_hcd? Also, try modprobing the other USB drivers, uhci_hcd and ehci_hcd, and see if it works then...

lsmod | grep ohci
ohci_hcd 19076 0
usbcore 116256 6 usb_storage,uhci_hcd,ehci_hcd,ohci_hcd,usbserial

and I've tried all manner of #s after sda

this is also kind of off

lshwd
00:02.0 USB Controller: Acer Laboratories Inc. [ALi]|M5237 (USB) (ohci_hcd)

whereis

hwd -s
Drive(scsi): SCSI device sda: 2037010 512-byte hdwr sectors (1043 MB)

I don't have a scsi drive, I'm on a laptop. Could it be possible it thinks this my usb stuff is scsi?[/code]

That seems normal to me - I get the same thing when I plug a USB stick in.

But when I try to mount using exactly the same set-up as you describe, it works. So there does seem to be something strange about your laptop or USB thingy. Have you got a good udev?

That's due to a bug in lshwd, a report has been posted.

What's in /dev?

what does 'dmesg' output when you run it?

as for hwd, you shouldnt need to use that now, just enable MOD_AUTOLOAD="yes" in /etc/rc.conf and you should be right

look in /dev both before and a minute or so after you plug the usb stick in and see if a new device has been created. Have you tried things other than sdaX, like sdbX, sdcX? Mine is usual sdc1, but that's because I have SATA hard drives on sda and sdb. However, I've also have it register as sdd and sde at times if I have made a mistake unmounting it or my palm or my camera.

See if you can run fdisk /dev/sda after you plug the drive in; that should tell you something.
