First, i want to say hello to everybody, as this is my first post on
this mailinglist!
I have a pontis sp600 mp3 player, which appears as a usb-mass-storage
device when connecting to the bus. hotplug is installed, so the scsi
emulation is started, and the bus shows up in /proc/scsi/ :
raphael@marvin:/proc/scsi/usb-storage-0$ cat 1
Host scsi1: usb-storage
Vendor: PONTIS Electronic
Product: SP600 - USB Audio Player
Serial Number: 0000000000000001
Protocol: Transparent SCSI
Transport: Bulk
GUID: 09bc00030000000000000001
Attached: Yes
everything seems fine until i actually want to access the bus via
/dev/scsi/host1/bus0/target0/ (note i'm using devfs)
as soon as i want to ls the scsi/host1/bus0/target0/lun0/ dir, ls is blocked
here's the syslog (starting with the messages when doing ls):

I think the problem lies somewhere with the STARTSTOP command. After
this, the usb driver seems to be messed up, so reconnecting the device
does not work. I'd be very glad if someone could help me with this problem.
Here are some environmental properties of my computer:
distro: Debian Sid (unstable)
Kernel: tried with 2.4.17 and 2.4.19-pre10-ac2
chipset: VIA686A
