I would not call that a solution because the devices are out there. > >> I hope this is enough info to get this working in mainline. > > > Not really, we need to find another way to identify the chip. > > It wouldn't be something you could find in /proc/bus/usb/devices, would it? I don't think so, I'm thinking more specific entries in the EEPROM. We would need a debug version that dumps the EEPROM before we load the firmware. We will have to find data at some offset, which reliably would tell us, whether we deal with a ZD1211B instead of a ZD1211. Just classical reverse engineering. If I have such code ready I would send it to you and I would need your dump. I happened to own the old PN18 and so we could compare the EEPROM contents and do something with this. But don't expect any working code before the weekend. > Ah, so you can't use a EAFP/trial-and-error approach (and LBYL is not an > option > due to the chip not making any mechanism available by which it can be > identified)? I don't want to try it, we had several problems with reloading issues. -- Uli Kunitz ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
