Hi Sergey,
ah, so much time I've let this problem without attention :(
I'm "responsible" of hidups (USB UPSs support) rewritte for
the Network UPS Tools project.

I think all the complexes devices which might be supported by hiddev
(ie other than joy/keyb/mousedev) might need this. This has to be
validated by others.
This means that your solution might be applicable with something
like (not yet tested):
void hid_write_report(struct hid_device *hid, struct hid_report *report)
{
if (hid->claimed & HID_CLAIMED_HIDDEV) {
hid->out[hid->outhead].buffer[0] = report->id; //XXX
hid_output_report(report, hid->out[hid->outhead].buffer + 1);
hid->out[hid->outhead].dr.wValue = cpu_to_le16(((report->type + 1) <<
8) | report->id);
hid->out[hid->outhead].dr.wLength = cpu_to_le16((report->size + 7) >>
3) + 1; //XXX
} else {
hid_output_report(report, hid->out[hid->outhead].buffer);
hid->out[hid->outhead].dr.wValue = cpu_to_le16(0x200 | report->id);
hid->out[hid->outhead].dr.wLength = cpu_to_le16((report->size + 7) >>
3);
}
hid->outhead = (hid->outhead + 1) & (HID_CONTROL_FIFO_SIZE - 1);
...
I'll try this and report it back ASAP. If you test it too, I'm also interested
in having feedback.
