Hi James,

I don't have lsusb on my mac. Here is the system_profiler part for the USB device I'm trying to use:

             USB Storage:

               Capacity: 2.03 GB (2,032,664,576 bytes)
               Removable Media: Yes
               Detachable Drive: Yes
               BSD Name: disk1
               Product ID: 0x0727
               Vendor ID: 0x05e3  (Genesys Logic, Inc.)
               Version:  2.07
               Serial Number: 000000000207
               Speed: Up to 480 Mb/sec
               Manufacturer: Generic
               Location ID: 0xfd360000
               Current Available (mA): 500
               Current Required (mA): 500
               Partition Map Type: Unknown
               S.M.A.R.T. status: Not Supported

Regards,
Anna.

Also, I just plugged in my USB 'stick' and it showed up as four devices under the /dev directory (you have to be a system administrator AND access this through Terminal.)

The following is the result of using the ls (list) with the -l (long format) command for these devices:

brw-r----- 1 <user> operator 14, 10 Feb 19 18:39 disk4
brw-r----- 1 <user> operator 14, 11 Feb 19 18:39 disk4s1

This is the block access (b) and the device is only read/write for me.

crw-r----- 1 <user> operator 14, 10 Feb 19 18:39 rdisk4
crw-r----- 1 <user> operator 14, 11 Feb 19 18:39 rdisk4s1

This is the character level access (c) and the same 'rights' are bestowed upon the device. You might want to try this with the device not plugged in and when it is plugged in.

You want to map the 'raw' level (in my case rdisk4) to a drive letter, if that is what the program requires. Otherwise, and if the program requires the use of a hardware Windows driver, you are out of luck trying to get this to work with Wine as it is now.
