The only immediate thing that stands out to me is that in 2.4 the INQUIRY is
'12 00 00 00 FF 00' (Allocation length 255), while in 2.6 it is '12 00 00 00 24 00' (Allocation length 36 (makes sense)).
I added an unusual_devs.h entry:
UNUSUAL_DEV( 0x0dbf, 0x0302, 0x0000, 0xffff,
"Addonics",
"USb to IDE Cable",
US_SC_DEVICE, US_PR_DEVICE, NULL,
US_FL_FIX_INQUIRY ),to bypass the INQUIRY command, thinking that it was not being liked by the reader, but now it just goes immediately on to the TEST_UNIT_READY command which fails in exactly the same way (1st 31 byte chunk OK, 2nd 13 byte chunk times out).
