Posted for others' sake. Updating drivers is not an obvious process... given the discussion at D-Light (successes) and my own success in internal testing, I thought directions for this fix needed publishing.

Uummm.... Did I give the impression that I didn't know how to update drivers??? or, are you posting for others sake? I have mine updated. That's why it is working properly for me now. No lagging.

XP instructions:
1. Get the drivers from here:
2. Click on Start
3. Right click on "My computer", choose "Properties"
4. Click the "Hardware" tab
5. Click "Device Manager"
6. Expand the section "Universal Serial Bus Controllers" by clicking its "+"
7. Find the device "USB Serial Converter".
8. Right click it and select "Update Driver"
9. Choose "No, Not This Time" and click "Next"
10. Choose "Install From A Specific Location" and click "Next"
11. Have "Include This Location In The Search" Selected and click "Browse"
12. Browse to and select the location where you downloaded the driver from FTDI
13. Click Next and proceed to install the driver
14. Repeat the above but this time expand"Ports (COM & LPT)" and update the driver for the corresponding "USB Serial Port (COM xx)"
A real pain, but it does fix the COM issues.
The upcoming D2XX Aurora looks good and does fix most of the COM issues as well, but even the D2XX version performs best on the latest driver, so an upgrade is recommended.
Maybe someone could rewrite these instructions for Vista/Seven?

No windows update.... I manually updated the USB serial port driver but forgot to update/forgot there was another part to the install. So the "USB serial port" was at 2.6, but the "USB serial converter" was left at 2.2.4. They must not like each other.
That is interesting info on the D2xx comm engine. Look forward to giving it a try.

I'm glad to hear that someone is getting a handle on what is going on.
So, your testing indicates that the device and VCP drivers are going out of sync due to a Windows update? We've been working on a D2XX based playback engine here which does not use the VCP driver at all. My own show is running on this beta engine tonight and it is a huge improvement over the old VCP based engine. There are still a few bugs with Firefly and WiLink, but we should have a version out of beta within the next couple days. The history on this update is long (it was originally written for 2.0, then was worked into 1.2, and now has been stripped of some features and wrapped into 1.0). Bonuses: better COM threading (heartbeat controlled by another thread so events at time zero will work properly), multiple Aurora instances can talk to the port at the same time. Stay tuned. |
