Hello 9fans,
I find problem!
New usb driver not configure file epXdata for writing or inputing, old
driver do this. Why this happen?
When I run usb/usbd -v -d I can see this:
.... maxpkt 64 interval 0ms [OUT] [Bulk] #usbd know about direction on this endpoint
.... maxpkt 64 interval 0ms [IN] [Bulk]
But when I ls -l /dev/usb0/1 I get this:
--r--r--r U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep1data #but not set direction for files
--r--r--r U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep2data
In old installation this looks like:
---w--w--w- U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep1data
--r--r--r-- U 0 rlab rlab 0 Sep 13 22:55 /dev/usb0/1/ep2data
When I set direction manually all works well:
echo -n 'ep 1 bulk w 64 32' >/dev/usb0/1/ctl
Thanks for help!
Sergey
