Howdy,
I have an interesting situation with 2 different TEAC FD-05PUB-x59
floppy drives. The x59 designation is on the external device label,
the two samples in my lab are -159 and -259.
Both show the same descriptors, and both indicate they are C/B/I
devices according to lsusb.
However, depending on the value defined in the unusual_dev list,
currently US_PR_CB, I can only get the older -159 drive to
configure.
If the unusual_devs list is edited to show the supported protocol as
US_PR_CBI, the device -259 configured, and not the -159.
This leads to my questions:
1) What is the the signifigance of the unusual_devs list. I am
infering the list exists to provide a way to configure devices
that do not precisely agree with the protocol actually supported
2) if a given device is in the unusual_devs list, how does one also
define that it might show as the other, that is to say, correctly?
