Subject: Re: [PATCH] usb-core: Add MS_INTR_BINTERVAL USB quirk

Thank you for your very helpful answer. I really do appreciate it.

It's possible that this device is using high speed because it offers a feature 
to transfer its internal clipboard to the host, and it allows that clipboard to 
contain lots of data. Interestingly, though, hidden within a usage note, they 
do observe that, so far, they've been unable to achieve a transfer speed faster 
than 5,000 characters in seven minutes. It looks to me like this is exactly due 
to their incorrect setting of bInterval. :-) I've sent them a note about it.
