I ran into something similar and it turned out to be that the terminal 
hardware only supported USB v1.1 and the USB v2.0 driver was interfering with 
identifying the flash drives. So, I eliminated loading the USB v2.0 driver in 
the LTSP kernel. Most USB v2.0 devices are backward compatible, so it has 
worked fine on both old and new flash drives now. The file altered were:

/opt/ltsp/i386/etc/rc.sysinit:

	< for MODULE in ehci-hcd uhci-hcd ohci-hcd; do
	---
	> for MODULE in ohci-hcd uhci-hcd ; do

and /opt/ltsp/i385/rc.usb:

	< for module in usb-uhci usb-ohci ehci-hcd uhci-hcd ohci-hcd
	---
	> for module in usb-ohci usb-uhci ohci-hcd uhci-hcd


You might try the same (make backups of the originals, of course).
