IF you're NOT using a Windows-supplied 1394 host controller driver, AND the vendor-supplied driver is working for you, THEN there's no reason to change it.
IF you ARE using the new Windows 7 1394 driver, I would recommend that you switch to the legacy driver. I've seen enough problems with the new Win7 13494 driver that I generally wouldn't recommend people use it until it's fixed. In general, vendor supplied drivers are sometimes better and sometimes worse than the Windows supplied drivers. Some vendor drivers are junk. Some vendor drivers tend to improve the performance of their devices (sometimes greatly) at the risk of overall system throughput (and often increased DPC latency). And still others are very competently developed and provide features that the Windows-supplied drivers don't. Unfortunately, the best solution can only be found through trial-and-error, Peter K1PGV > -----Original Message----- > From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex- > radio.biz] On Behalf Of Neal Campbell > Sent: Sunday, October 24, 2010 2:00 PM > To: Tim Ellison > Cc: flexradio@flex-radio.biz > Subject: Re: [Flexradio] Legacy vs. Current (?)
