I've got a USB to serial adapter that I picked up from Radio Shack earlier this year. The updated pl2303 driver is already in the mainstream kernel as per https://bugzilla.redhat.com/show_bug.cgi?id=429652 but I'm not getting much traction from Red Hat as far as them updating the kernel. So every time there's an updated kernel, I have to rebuild the srpm. I figure that this is the kind of si...

    Lately I replaced my 10+-year-old server with a nano-ITX-type one that has USB but not old serial ports.  I connected my FE700VA to DB25-to-9-to-USB cables, but haven't been able to set it up. Apparently my DB9-to-USB cable (Prolific Technology, Inc. PL2303 Serial Port) has issues needing old software (setserial?) and some new software (fconfigure) being changed.  Has anyone managed to do something like this?     I'm still also interested in knowing how to control the three UPSes I have in the house (except FE700VA not re-setup yet) over the n...

Hi, is there a way to use my Belkin F6H650 on the USB port? I already installed usbhid-support, but neither the hidups worked (reports "/dev/usb/hiddev0 is not a UPS") nor genericups with upstype=7 and the hiddev set as device ("ioctl TIOCMSET: Invalid argument") worked. I have installed the debian sarge package of nut 2.0.1 (2.0.1-4) Regards, Philipp
