help knoppix cant see my usb drive have read all faqs

hello, i'm new to linux, using knoppix on new systemax tourbook laptop
when i run knoppix from cd it boots up fine and recognises usb (or at least mentions usb) during loading but once i get into it, the system
can't see my usb drive. my hard drive comes pre-mounted as hda1, where is the usb drive? i read the faq, there is no sda or
sda1,there is a dev/usb/ but with millions of entries so how do i know which is the usb drive, do i have do mount it myself and
if so how ?
have read stuff here and tried things
when i run lsusb i get
bus 003 device 001:10 0000:0000
bus 002 device 001:10 0000:0000
bus 001 device 001:10 0000:0000
if that's any help. as you can see i don't know what i'm doing so idiotproof instructions would be great!

thanks
mary :shock:

If you run "dmesg" in a console you can look for lines like this:

USB Mass Storage support registered.
hub.c: new USB device 00:10.0-2, assigned address 5

To see if your drive has been found. You can then mount it yourself with mount /dev/sda6 /mnt/sda6 (tho with the number of the partition you want).
I had a problem lately where the ehcd-hcd module was preventing my usb drive from working. You can try removing that module with rmmod ehcd-hcd and disconnect and reconnect your usb drive and see if it was found.

Try to boot another machine with Knoppix and conncet the USB drive there. I have had many USB dispositives.

1 Usb 1.0 64 mb thumb disk Cigarr Pro, work flawlessly
1 Usb 2.0 128 mb thumb disk Apacer, no way in Linux
1 Usb 2.0 256 mb thumb disk gneric, no way in Linux (appears in the desktop but the system was unable to read it)
1 Usb 1.0 IDE enclosure generic, no way in linux
1 Usb 2.0 IDE enclosure generic, work flawlessly

So, is a tricky task. Some USB work without a glitch, another need more work

thanks, that's just the kind of precise info i needed.

aha i never thought it could be the usb drive itself... its a bytestor 128mb usb 2 i suspect by the build quality that it's at the lower end of the market... will try on my dad's machine and then get my muvo back from my brother and try that one too. thanks for the tip.
