[Gnuk-users] USB Suspend

[NIIBE Yutaka]

Hello,

I leanred USB suspend in the USB specification 2.0.  IIUC, suspend is
not well defined in USB 1.1, but more clearly defined in 2.0.

I tried to implement USB suspend for Gnuk, adding new function
chopstx_conf_idle to Chopstx.

By the spec, power consumption on suspend mode should be minimized.  Up
to 2.5mA is OK.  I tried, but I don't know how much it is.  I need some
USB meter now.
