[Nut-upsdev] NUT usbhid -- trying to write USB (sub)drivers
Hi Rok, I retired from working on NUT a few months ago, so I don't have the most up-to-date info. But the guys on the nut-upsdev mailing list (cc'd above) are very helpful. Both of your devices (or nearly identical ones) have been seen on the mailing lists before. The Sweex was first mentioned in a message by Eli Wapniarski on 14 Jun 2006 on nut-upsuser, and was most recently discussed in a message by Peter van Valderen on 20 May 2007 on nut-upsdev. The PowerMust device was discussed by Carlos Rodrigues on the nut-upsdev list on Fri, 14 Apr 2006, and by Guillaume JAOUEN on nut-upsdev near 16 Feb 2007. Note that these devices may be packaged under a different name, but it's still likely the same device. As far as I remember, the Sweex uses an unknown protocol, and the PowerMust probably is (or can be) supported by the megatec_usb driver. Neither device uses the HID protocol, and therefore neither will be supportable by a usbhid-ups subdriver. -- Peter Rok =?utf-8?q?Pape=C5=BE?= wrote:> > Hello Peter. > > I've noticed that 2 of my UPSes: > 1.
