I'm using product ID=3D0x772b (ASIX Electronics Corporation, an AX88772B 10= /100) while Dmitry is using 0x7e2b (we're using the same vendor 0x0b95), and both devices are regarded as AX88772B. Unfortunately I was responding to the interface ue0 as being the problem. Regardless, we aren't comparing apples = to oranges - as I am getting successful connections albeit with bad cksums; wh= ich I continue to get after disabling pf (via pfctl -d) References: Note from /usr/src/sys/dev/usb/net/if_axereg.h * This driver does not enable partial checksum feature which will * compute 16bit checksum from 14th byte to the end of the frame. If * this feature is enabled, computed checksum value is embedded into * RX header which in turn means it uses different RX header format.
