US_FL_FIX_CAPACITY : It didn't work without it, BUT I have opened the disk as
"physical disc"
with Hex Workshop under win xp now, which says the last sector is 38997487 and
under linux
dmesg shows "SCSI device sda: 38997488 512-byte hdwr sectors (19967 MB)"
without patch.
So this would be ok.
Therefore I have tried to hard code max_sectors_kb to 64 in scsiglue.c and it
surprisingly works.
Either I can make a patch to hard code it or somebody could add this feature
to "unusual devices",
because I think I'm not advanced enough to do it on my own.
US_FL_IGNORE_RESIDUE : I used usbsniff under windows to log the traffic and
see yourself
[2723 ms] <<< URB 1056 coming back <<<
-- URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER:
PipeHandle = ff9b4c64 [endpoint 0x00000082]
TransferFlags = 00000003 (USBD_TRANSFER_DIRECTION_IN,
USBD_SHORT_TRANSFER_OK)
TransferBufferLength = 0000000d
TransferBuffer = feef7d80
TransferBufferMDL = ffb36890
00000000: 55 53 42 53 38 9b a2 ff 01 9f 51 06 00
UrbLink = 00000000
It always returns 01 9f 51 06.

No Idea, because I have only an EasyLite DJ 20. So in fact, I could not even
say if
they have the same ProductID & VendorID, although it is probably for the
Easylite DJ20
and the Typhoon DJ1820. But after googling again i'm not sure if TGE is also a
manufacturer
of this device or if the device only includes some units from TGE, because TGE
doesn't
provide this device on their site. So perhaps the patch should be

Perhaps the firmware is from TGE only ?!
And please note that I have testet it again with US_FL_GO_SLOW and without it.
The device still
crashes without it after some time.
