Something I've meant to ask for a while... What about things that apply
to an entire interface or device, as opposed to a single endpoint?
In addition to sending or cancelling URBs, usbfs allows users to:
Issue a USB port reset to the device;
Find out the name of the driver bound to an interface;
Unbind a kernel driver from an interface;
Find out the device's address and speed (although it doesn't
distinguish between full and high);
Change the altsetting for an interface;
Change the device configuration;
Claim (bind usbfs to) an interface;
Release (unbind usbfs from) an interface.
Other things that might be nice but currently are not included are:
Get the current frame number;
Suspend the device's upstream port;
Resume the device's upstream port.
How will usbfs2 address all these capabilities?
