Hi,
I am trying to use an MGE Pulsar Extreme UPS with the NUT port using the
newhidups driver.
I can read the values just fine but I can't set anything which precludes the
PC from shutting the UPS off (or in fact configuring it in any way). The
error is...
...
Looking up DelayBeforeStartup
usb_control_msg: 161 1 791 0 0x514f34 8 4000
Report : (8 bytes) => 17 FF FF FF CB 1F 51 0A

PhyMax = 0, PhyMin = 0, LogMax = 65535, LogMin = -1

==> Report after setvalue: (8 bytes) => 17 0C 00 00 CB 1F 51 0A
usb_control_msg: 33 9 791 0 0x514f34 8 4000
USB error: error sending control message: Input/output error
Set report failed
FAILED
Shutoff command failed (setting ondelay)
...
This program uses libusb to talk to the UPS over ugen - the system has 6.0 on
it and libusb 0.1.12 (the latest).
I am going to try instrumenting ugen next and see why it's returning EIO.
I checked CVS but I don't believe any of the commits since 6.0 would have an
effect here.
Does anyone have any suggestions?
Thanks.
