GTT70A RS232 Driver Problems
Posted: Wed Mar 18, 2020 8:19 am
I have a GTT70A-TPC-BLM-B0-H1-CS-VPT display that is being uncooperative. After working with support yesterday I was able to get the GTT Bulk Storage device in the device manager. This morning it's not there anymore and instead it shows up in the Disk drives section as "Matrix Orbital GTT Disk USB Device". When it shows up this way, I can access it from File Explorer but it's named "GTT20". GTT Designer is unable to recognize it, probably because it's expecting it to be the Bulk Storage thing instead.
I followed the instructions from a similar thread that suggested installing WinUSB drivers manually. I grabbed the latest copy of Zadig and tried to install them that way. By checking the "show all" option, I was able to find GTT Mass Storage Device in the list of options. It's using USBSTOR driver by default.
Changing to WinUSB Removes the entry from the Disk Drives section and adds a USB device that matches the name from Zadig.
GTT Designer is still unable to connect and now the storage is not visible as a drive in File Explorer.
Details:
Windows 10 Enterprise x64 1803
GTT70A R3.0.2 serial 20M01-2188
I'm really frustrated with this. USB drivers shouldn't be this complicated in 2020.
