mounting a USB 2.0 Mass Storage connected into USB 1.0 UHCI Hub (linux)

Hi;
I have two USB 1.0 EHCI hubs (with 2 channels every one)in my machine. Their speed is 12 MB/s.
My OS is Linux Fedora Core 1.0.
I connected into it an USB 1.0 mass Storage, so I can mount it
(via that command #mount /mnt/flash/).
Recently, I connected into it an USB 2.0 mass Storage, but I can't mount it.

I taped:
#mount /mnt/flash/
mount: you must specify the file system type.

I formatted my USB mass Storage to FAT32, and I taped:
#mount -t vfat /dev/sda1 /mnt/flash/
mount: fs type incorrect, incorrect option, incorrect superbloc in /dev/sda1, or too many file systems are mounted.

In /etc/fstab, I found that line when I connect the mass storage:
/dev/sda1 /mnt/flash auto noauto,owner,kudzu 0 0

Do you think there is an incompatibility between USB 1.0 EHCI hubs && USB 2.0 mass Storage?
Is there any solution(a driver to install, for example)?

Thanks...

(^^;?(I'm unsure of this.)

Apart from your case, there seems to be many non-mount problems, i.e. USB1.0 only or MO or CD-R etc..

Against it, someone advises to plug and unplug several times.

Someone advises to introduce particular modules, and someone advises to recompile the kernel.

However, if you formatted it from Windows, what about fdisk and formatting it from Linux again?

Monologue: A few years ago, I installed Peanut linux and was very happy with its compactness and its appearance. But soon I found that I couldn't mount floppy. It was extremely critical, so that I made any possible effort as far as I could in vain. I was made to uninstall it.

what does
fdisk -ul /dev/sda
tell you? How did you partition it (one big extended, one big primary) Is it showing up in /proc/scsi device list (/proc/scsi/usb-storage0/)? Does lsmod show the usbstorage module installed?
