Re: [PATCH 1/2] Increase HID_MAX_BUFFER_SIZE to 8KB to support additional, devices.

[Dean Camera <dean@fourwalledcubicle.com>]

Sure, I'll do that now (and do the same for my other unreviewed patch, 
which adds additional ioctls(). It's suprisingly frustratingly difficult 
to get Thunderbird to send a one-time unformatted plain-text email, as 
it seems to be a global setting that has to be changed.

I've given up on that and just set up git-send-email, which I've never 
used before but hope doesn't mangle anything.

Cheers!
