Hello,

I recently got a Bafo USB to Serial adapter (BF810) which came with driver for Mac OS 8/9, but not for OS X. Any one has any generic USB->Serial driver that I can test with.
I wrote to support@bafo.com.tw, but no response from them (wrote them again today).
Any help is much appreciated.
BTW, where would I look for writing device drivers for OS X. Thanks

I have an Entrega/Xircom USB-serial converter with the same problem, and I have given up on it. I spent quite a long time fiddling with it, and discovered the following:

1. There is no such thing as a generic USB serial driver. The adapters are all completely different and need completely different drivers.
2. Xircom/Intel will not release any of the technical details you need in order to write a driver, even though the product has been discontinued. Bafo may be different.
3. The device needs firmware downloaded to it when it is plugged in before it will work, and this firmware is not available. An indication of this is that the device id is different under OS9 (with a driver) from OSX (without a driver).
4. Writing serial drivers for OSX is complicated and badly documented.

If you can get past these hurdles, the info on how to write device drivers is in the developer documentation (look in Kernel/IOKit). Good luck.

Barney.
