tonhe98 Posted April 7, 2010 Share Posted April 7, 2010 Ok, I have a Keyspan 19HS USB->Serial adapter, that works just fine under SL on my MBP. But, when I attempt to use it on my i7 Hackintosh (ex58-ud5 mobo) the drivers never register the device. I've contacted Keyspan, and they have no clue whats up. At this point in time I have no clue what steps to take to even being finding a fix for this. Here is a screengrab from system profiler.. http://i.imgur.com/zlWEU.png Link to comment https://www.insanelymac.com/forum/topic/214967-issues-with-usb-serial-adapter/ Share on other sites More sharing options...

Fissehans2 Posted August 21, 2011 Share Posted August 21, 2011 There are several companies that makes usb serial adapters, the most commonly used chipsets used are: FTDI Prolific WCH Silicon Labs Prolific is the cheapest but also the worst, the drivers/chipset are simply incompatible with many devices and operating systems, including 64-bit systems, (even Prolific themselves actually does provide a 64-bit driver), they are simply too cheap and unstable. The best chipset/drivers are the FTDI. These are very solid and compatible with most devices and almost all operating systems both 32 and 64-bit. These usb serial adapters are a bit more expensive but well worth the money.
