Hi,
I have a GQ-4X eprom programmer which I bought ~4-5 months ago from ebay user mcumall_electronics_inc. It worked fine until this morning, today I plugged it in to my pc and pc says that "USB Device Not Recognized"... I tried reinstall drivers and software, use another pc, different USB cable, but I get the same error message from pc... even USBprg software says "Did not get response from programmer. Demo only."
Any help on that?

The device is failing to enumerate itself to the system, so Windows doesn't know what driver to load. Dump from usbview:
Device Descriptor:
bcdUSB: 0x0000
bDeviceClass: 0x00
bDeviceSubClass: 0x00
bDeviceProtocol: 0x00
bMaxPacketSize0: 0x00 (0)
idVendor: 0x0000
idProduct: 0x0000
bcdDevice: 0x0000
iManufacturer: 0x00
iProduct: 0x00
iSerialNumber: 0x00
bNumConfigurations: 0x00
ConnectionStatus: DeviceFailedEnumeration
Current Config Value: 0x00
Device Bus Speed: Low
Device Address: 0x00

A typical device (in this case, an IBM mouse):

Device Address: 0x03
Open Pipes: 1
Endpoint Descriptor:

| I think you need to send the programmer back for the exchange. Contact support@mcumall.com for assistant. |
