IMSProg cannot connect to EZP2023+ on Linux
Distribution
Ubuntu 24.04
Architecture
amd64
Kernel version
6.14.0-35 generic
IMSProg version
v1.7.1
Bug description
Hi, I'm trying to use IMSProg on Ubuntu 24.04 with an EZP2023+ programmer. IMSProg displays “Not Connected”, and when running it from the terminal I get:
Couldn't open device 1a86:5512.
What I see on my system
The device does not enumerate as 1a86:5512. Instead, when plugging the EZP2023+, the kernel reports:
idVendor=1fc8, idProduct=310b Product: WinUSBComm Manufacturer: www.zhifengsoft.com
lsusb shows:
Bus 001 Device XXX: ID 1fc8:310b www.zhifengsoft.com WinUSBComm
So IMSProg expects a CH341A-compatible device (1a86:5512), but my EZP2023+ identifies itself as a completely different USB device (1fc8:310b), which causes IMSProg to fail when opening it.
What I expected
Since the project documentation states that EZP2023 is supported, I expected IMSProg to detect this device or at least handle this VID/PID variant.
What I've tried
Different USB ports (USB2 / USB3)
Direct connection (no hub)
Different cables
Creating a udev rule (no effect, since the expected VID/PID is different)
Running with sudo
Running the software from terminal to get the exact error
Suggestion
It looks like the EZP2023+ model I'm using uses a different USB bridge (Zhifengsoft WinUSBComm instead of CH341A). If IMSProg intends to support the whole EZP2023 family, this VID/PID might need to be added together with the corresponding USB protocol.
I'd be happy to test any build or provide additional logs if needed.
Thanks!

Hello, @sergiojoker11! IMSProg only supports the CH341A programmer. I will consider supporting CH347 and FT232H devices in the future. Nowhere in the documentation is there any mention of support for EZP series programmers, except that the chip database structure was borrowed from software for these programmers.
