I use the USB VGA adapter(for a 3rd display) on a HP laptop running Win 7 Home Premium 64 bit for about a year. The 2nd display is connected to the VGA port of the HD 6550 video card.
Starting last week, it was acting up. Basically, windows can’t see or extend to the 3rd additional display. I reinstalled the driver 5.6M2 (also tried the latest 6.3), and it worked again once, each time right after new driver is installed.
As soon as I reboot the machine, it didn’t work agan. It seems to work best the first time when the DisplayLink Manager recognized the new display and installed the driver.
I checked these
The displayLink Manager is running, under Services and under Task manager
Under Device manager, you can see USB Display Adapters - Plugable USB-VGA-165 - its Hardware Ids are USB\VID_17E9&PID_037B&REV_0101
But during one of the subsequent USB device driver installed (when plug in), I could see it as DisplayAdapter(8060) installed in the popup, which indicates it may have some kind of problem loading the driver.
I have tried both the 5.6M2 as recommended on Plugable page and the 6.3, the latest driver from DisplayLink which also supposes to work. I unplug the USB, went to add or remove programs to uninstall DisplayLink software and then use the download to install it back before plugging the USB back in.
Both works ONCE… the very first time after you installed the driver and plug into the USB.
I have also change cables, monitors and the problem is repeatable.
I uninstall the USB-VGA-165 adapter within device manager. Unplug the USB, shutdown, start up the machine, then plug the USB back in. It searches for driver via windows update and got the 5.6 driver and bring the 3rd display back to work.
Thanks for posting here! I’m sorry to know about the trouble you are having. Let’s figure out what is causing the issue and how to resolve it.
We do not recommend using the DisplayLink 6.3 drivers as we are aware of various issues caused by it. Our recommended DisplayLink driver for USB 2.0 is 5.6M1 as it is the most stable version for DisplayLink based USB 2.0 Graphics Adapters.
If the current version of driver installed on the system is 6.3, I’d recommend uninstalling it and installing the 5.6M1. Here are the steps to do that:
I also noticed after a few reboots. Unplug and replug, it was trying to find the USB driver, couldn’t find it, then went online and get 6.1 all without my help.
The Graphics software is still 5.6 but the Core went to 6.1
How come I see the DisplayLink Manager icon on the task bar sometimes but not other times?
Is it supposed to be there all the time? Or does it only show up during the first time setup?
Basically, when I see that icon, it means the USB device is recognized correctly as a display adapter and 3rd display is connected and I have control over it. I just can’t figure out why it shows only some of the time.
