Null modem cable adapter for linux USB use
I want to dicth our last (oldest) desktop which has a serial connector. So I need an adapter for a USB connector or a null modem USB cable for configuring our firebox's. It must work with ubuntu. Any recommendations?
I thought I might take a gamble on this one:
I bought pretty much the cheapest one I could on Ebay. Worked fine in Ubuntu. Had a permissions issue in Xubuntu and Mint but easily fixed once I realised what was happening.
I have no idea who it's made by, some unknown Chinese manufacturer.

Why not go with a serial card for about $20 and skip any potential USB hassles?
I'm using one of these (not from this seller, but the item listing on ebay has already ended): http://www.ebay.com/itm/RS-232-RS232-Serial-to-PL2303HX-USB-Adapter-Cable-Converter-for-Linux-WIN-7-/370891405155?pt=US_Parallel_Serial_PS_2_Cables_Adapters&hash=item565ad9b763
It works in debian (therefore 99% of other linux distros (troll bait for redhat/suse users)) and is detected as:

Make sure it says HXSP-2108D on it (see auction pic). Windows (oh the horrors!) and mac (no comment) drivers can be found here: http://www.prolific.com.tw/US/CustomerLogin.aspx (user + pass are guest >>>SAYS SO RIGHT THERE<<<). Left side, select usb smart io controllers > usb serial/parallel, 2303 and drivers.
Dunno about macs since I'm allergic to them but in linux it's just plug it in, fire up putty, select serial, use device /dev/ttyUSB0 set speed (SAVE THESE so you don't have to do it again) and open. It works perfectly everytime.
Looking back through my Ebay history I see the adapter I have is still available from the same seller:
Though mine is green(ish). For £2.75 including delivery it's hard to go wrong! ;)
Yep that's the one I use too. Works flawlessly under kubuntu and win 7 too. It's also sold here in shops under band name "Delink". Nice the long usb cable.
stephen you save me some money! I opened your link to that cable on ebay and thought that looks so familiar. A hunt through some draws and a ten mins later I found it and its working great (once I realised had to run as sudo).
