[BRLTTY] HIMS Braille Sense does not work

>The file dmesg-bs.log is with braille sense.

I believe the earlier conclusion that the Braille Sense is being seen as a hard 
disk to be incorrect. That part of the log is referring to a different USB 
device.

Here's what happens when the kernel sees the Braille Sense:

>[  323.906255] usb 2-1.3: New USB device found, idVendor=045e, idProduct=930a
>[  323.906259] usb 2-1.3: New USB device strings: Mfr=0, Product=0, SerialNumber=0

This is already wrong. I know for sure that the Braille Sense has correctly set 
manufacturer, product, and serial number strings.

>[  323.906387] usb 2-1.3: configuration #1 chosen from 1 choice
>[  337.668384] usb 2-1.3: USB disconnect, address 5
>[  341.699074] usb 2-1.3: new high speed USB device using ehci_hcd and address 6
>[  341.791543] usb 2-1.3: config 1 has an invalid interface number: 1 but max is 0
>[  341.791547] usb 2-1.3: config 1 has no interface number 0

The last two lines (above) indicate a serious problem. Something is going wrong 
when the Linux kernel is reading the USB configuration descriptor of the 
Braille Sense. The read itself is successful, but the data read in is corrupt.
