usbdi_util.h (1.29), uhid.c (1.62), ugen.c (1.68), usb_subr.c (1.114)
Yes, some devices return incorrect lengths in their string
descriptors. Rather than losing, do what Windows does: just
request the maximum size, and allow a shorter response. Obsoletes
the need for UQ_NO_STRINGS, and therefore these "quirks" are removed.
usb_subr.c (1.116)
In the "seemed like a good idea until I found the fatal flaw"
department... Attempting to read a maximum-size string descriptor
causes my kue device to go completely apeshit. So, go back to the
original method, but allow the device to return a shorter string than
it claimed.
