USB Flash memory based mp3 player problems. Tried but failed.

Hello,

FreeBSD lolownia 5.4-STABLE FreeBSD 5.4-STABLE #4: Sat Jun  4 01:54:40 CEST 2005
cvsupped today. Basically a GENERIC kernel with hw i don't need commented
out.

I have Samsung's YP-55 MP3 player. When I try to copy a file to it,
the process hangs for a while, and then kernel produces:
umass0: BBB reset failed, STALLED
umass0: BBB bulk-in clear stall failed, STALLED
umass0: BBB bulk-out clear stall failed, STALLED

System becomes not responsive (blocking a lot on i/o), even after pulling
the device out. Reboot mandatory.

I found several threads in google describeing this problem. Tried to follow
the instructions and:

1. Added my YP-55 to sys/dev/usb/usbdevs
 /* Samsung products */
 product SAMSUNG ML6060         0x3008  ML-6060 laser printer
+product SAMSUNG YP55           0x500d  YP-55 MP3 Player
2. Added entries for quirks suggested there:
+++ umass.c
+       { USB_VENDOR_SAMSUNG, USB_PRODUCT_SAMSUNG_YP55, RID_WILDCARD,
+         UMASS_PROTO_SCSI | UMASS_PROTO_BBB,
+         NO_INQUIRY | NO_GETMAXLUN
+       },
3. Added scsi quirks for it (also suggested in google)
+++ scsi_da.c
+       {
+               /*
+                * Samsung YP-55, rev 1.10/0.01, addr 3
+                */
+               {T_DIRECT, SIP_MEDIA_REMOVABLE, "Samsung Electronics"
, "YP-55 M
P3 Player", "*"},
+               /*quirks*/ /*DA_Q_NO_SYNC_CACHE*/ DA_Q_NO_6_BYTE
+       },

I tried these in various combinations, with DA_Q_NO_SYNC_CACHE,
with DA_Q_NO_6_BYTE, without scsi quirks at all, etc.
All failed.

I have even downloaded a 36mb linux kernel source just to find out my player
is not present in their drivers/usb/storage/unusual_devs.h .

As a last resort, I'm asking for help here.
Any hints?

I'm attaching some logs. (sorry it got thaat long)

Here is debug data with hw.usb.uhci.debug=7

A little less interesting, but maybe useful log:
