modprobe and module problems

I recently noticed that my USB devices didn't work all of a sudden, so I figured I'd play around, test a few things, it doesn't appear in /dev. I figured I'd try a few things,

modprobe usb-storage

etc.

I got this error:

FATAL: Could not load /lib/modules/2.6.30-ARCH/modules.dep: No such file or directory

So I googled it, then ran

depmod `uname -r`

And that didn't throw an error, a quick check to see if it worked then returned:

$ modprobe usb-storage
FATAL: Module usb_storage not found.

Now I have no idea what to do, this all worked perfectly earlier, since I had to modprobe pcspkr shortly after boot to fix my system beep, I did run a full update though. I include the related section of pacman.log

Re: modprobe and module problems

OK, this is really beginning to annoy me now, I gave up waiting and decided to try a few things, starting with reinstalling all my packages:

[b]$[/b] pacman -Qqe | grep -vx "$(pacman -Qqm)" | xargs pacman -S --noconfirm

That worked wonders, but unfortunately:

[b]$[/b] modprobe usb-storage
FATAL: Module usb_storage not found.

My problem persists, in fact:

[b]$[/b] cd /lib/modules/2.6.30-ARCH
[b]$[/b] ls -r
modules.usbmap       modules.pcimap     modules.ieee1394map  modules.alias.bin
modules.symbols.bin  modules.ofmap      modules.dep.bin      modules.alias
modules.symbols      modules.isapnpmap  modules.dep          misc
modules.seriomap     modules.inputmap   modules.ccwmap

Or in short, there are no modules in there, it's not that it just can't find them

Have you modules on /lib/modules/2.6.31-ARCH?

Re: modprobe and module problems

Well, that is strange(Sorry for looking in the wrong dir), the modules do exist, and they are found in modules.dep there's a huge list of them(which as far as I can tell are all there), but modprobe still gives me problems.

[b]$[/b] grep cdrom modules.dep;  modprobe cdrom
kernel/drivers/block/pktcdvd.ko: kernel/drivers/cdrom/cdrom.ko
kernel/drivers/cdrom/cdrom.ko:
kernel/drivers/ide/ide-cd_mod.ko: kernel/drivers/ide/ide-core.ko kernel/drivers/cdrom/cdrom.ko
kernel/drivers/scsi/sr_mod.ko: kernel/drivers/scsi/scsi_mod.ko kernel/drivers/cdrom/cdrom.ko
FATAL: Module cdrom not found.

[b]$[/b] grep pcspkr modules.dep; modprobe pcspkr
kernel/drivers/input/misc/pcspkr.ko:
FATAL: Module pcspkr not found.

I'm almost ready for giving up on this and reinstalling.

Re: modprobe and module problems

What is the output of dmesg if you plugin an USB device?

Re: modprobe and module problems

And I presume you have rebooted _after_ your kernel update?
Looking at your posts - I would say that is your reason - otherwise /lib/modules/2.6.30-ARCH would no longer exist.
You are still running a 2.6.30 kernel, but you no longer have any modules to go with it.

That was the problem. I realised shortly after making my last reply(then I couldn't find this thread to update it).

I was used to ubuntu, where kernel updates still leave the old kernel.
After making sure I reinstalled the newest kernel(because I'd tried rolling it back and stuff, not the best idea since there wasn't a real problem) I rebooted and it was all good(had a slight problem with GDM, but nothing I couldn't handle).

Sorry so much for taking peoples time on this issue, I should have realised it was a kernel version issue long before posting it here.
