Kirill, thank you very much for the test. > Currently the problem is when UPS is attached as /dev/updX, apcupsd > stops working. So shpuld /dev/upd be enabled by default?

I don't know, my current needs are just for USB devices, iirc modbus works over rs232 and tcp. A driver for ups based on tcp-connection the doesn't sounds to have a chance to get into base. Do you have this kind of device? let me know. > As it looks to me, this driver is going to have half of apcupsd usb > devices support to be really useful. It has been tested with the two devices we already have in usbdevs_data.h: http://bxr.su/OpenBSD/sys/dev/usb/usbdevs_data.h#621 -a
