System hangs after removing USB Memorystick

[Ben Ben]

When i remove my sub-memory stick after unmounting it,
my Powerbook G3 (Bronze) hangs up and the only possibillity is
to siwtch it off an on again.

I hope you can help me because this makes it impossible for me transferring data via my usb-stick.

The Problem also occurs if i remove other usb-devices that worked on runtime like the usb-mouse, no matter which of the two usb-ports i use.

It sounds like you might be getting a kernel panic-it may not be releasing the drivers properly. Check your system/kernel log files for any errors-they should all be date/time coded so you should be able to pinpoint the time when it locks up. Also have you been on a virtual term to see if any messages come up when either trying to unmount it or as you remove the device

What do you actually mean by this?
If i unmount it, i'm in a virutal terminal. but i didn't see any message coming up.

EDIT: The only thing i found was in messages is:
usb.c: USB disconnected on device 10:19.0-1 address 2

this time the system worked correctly.
But when i replugged i hangs up. The message therefore (it's the same as during boot with the usb-stick plugged already in before bootin):
hub.c: new USB device 10.19-0.1, assigned address 3
usb.c: USB device 3 (vend/prod 0x58f/0x9380) is not claimed by any active driver
#than there is sth. about SCSI Emulation for the USB thats fine so far an ith show the right data for the USB Mass Storage Device

And even if the USB-Stick worked after restart, up to now i even can't mount it because "sda1 is no valid blockoriented device

how was the memory stick formatted?

i had problems with mine getting data to read under windows, etc.

I found out that formatting it as superfloppy was
the best way for me.

Never had a problem since.

i think it was standard windows FAT. It worked without any problems before. The only thing was the crash after removing.
Or do i have to do anything else than unmounting bevore removing any usb-device? Because with the USB-nouse its the same.
