USB memory stick not recognized


I try to plug in a TwinMOS Modile Disk IV 1GB memory stick.
The stick is formatted with FAT32.
Mandrake 10.2 (2005 Limited Edition) doesn't recognize the stick.
Appears a window with title :
KWrited - Listening on Device /dev/pts/0

and the contents of the window :
Message from syslog@localhost at Tue Mar 28 20:00:32 2006
localhost kernel : Disabling IRQ #21

This window remains on the screen even if I remove the stick.

When the stick is plugged in , if I run harddrake, appears Detection in progress ... (and remains on the display ). If I remove the stick , the message from harddrake goes off and apperas the window with hardware components(normal window of harddrake)

Thank you,

i can share my experience with TwinMos II 512 MB. i insert it and in console the kernel message arrives the device is not accepting address 2/3/4/5 etc with the error code -110. after a long suffer i discovered that in my BIOS the option automatically assign usb irq is disabled. after turning it enabled my pendrive starts getting it. your problem syms like:
localhost kernel : Disabling IRQ #21
go to console and type lspci -v|grep HCI this will show all Host controller interface for usb. pci is the bus of usb.

i was absolutely benefited by the site, specially from their FAQ. they first tell to touch the bios. they mentioned most often bios fix solves the problem.

please go to your bios and find if IRQ 21 is disabled. if it is, enable it. i hope it will solve your problem.
