I've never found any one particular USB-Serial Adapter to be any more reliable. Currently using the Tripp Lite Keyspan, Model USA-49WG, SKU CU8037. Appears on the USB chain as: Product ID: 0x0131, Vendor ID: 0x06CD. Still kernel panics when I pull out the USB Cable.

I carry a Dell Laptop when going to customer sites+Putty for consoling into Cisco Routers because I've never found a Serial Cable/USB combination that doesn't cause the Macbook air to Kernel Panic.

I'll give the PL-2303 based device a chance - I see there is a nice comparison site here:

I'll definitely try the Trendnet TU-S9. Here's hoping 4 years of weekly hell on my mac laptop comes to an end...

But, maybe I'll try upgrading to Mavericks - this seems to suggest that some progress has been made in the FTDI driver department: https://developer.apple.com/library/mac/technotes/tn2315/_in...
