Hi folks,
I saw that a problem related to this has already been posted to this
list sometime in 2003, but no answers have been given.

I just bought an USB 2.0 Flash Drive (Microspot). When I plug it in, I
get these messages on the console:

umass0: PNY USB2.0 FlashDisk, rev 2.00/0.50, addr 2
da0 at umass0-sim0 bus 0 target 0 lun 0
da0: < USB2.0 FlashDisk 1.1b > Removable Direct Access SCSI-0 device
da0: 1.000 MB/s transfers
da0: 248 MB (507904 512 byte sectors: 64H 32S/T 248C)

And this is good, because the information is correct.
But after this, it prints 7 times on the console the following:

umass0: Phase Error, residue = 0
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi
status == 0x0 

which is not good.

The problem is that I can mount the device:
# mount_msdosfs /dev/da0s1 /pen

and I can read & write files on it, without any kind of problems.

I have this in my kernel:
# USB support
device          scbus
device          da
device          pass
device          uhci
device          ohci
device          usb
device          umass
device          ugen

Any advice is appreciated!

Thank you, best regards!
