Hi!
I own: 02:00.0 Ethernet controller [0200]: 3Com Corporation 3c905 100BaseTX [Boomerang] [10b7:9050]
It's unsupported: ---[code]--- Error: No supported PCI device found. Error: Programmer initialization failed. ---[/code]---
I would love to help You to get it to work with flashrom. Do You need it?
Regards!
