Assalamualaikum and selamat sejahtera.
I'm having nightmare today when my QHY5 suddenly disappear from my windows hardware list (COmputer Management)
Unplug and plugin, only gave "USB device", which resulted "Unknown Device" under "Other Devices"
It happened to me before, and somehow I forgotten the steps. So today, I have retraced back, and put it into writing here for our reference in the future.
I quote from Dr.Qui post at
qhyccd.com forum
Hello,
Here is the standard solve method to solve this problem:
You need prepare a XP computer.
0. Check the VID/PID If it is not 04b4:8613. Go to step 1 . If it is 04b4:8613 . Goto step 2
( we supposed the vid/pid is FF18:0901, for example )
1 . uncompress the driver.rar. And there is a .inf file. Please edit it . change all 1618 0901 into the FF18 0901 (There is three position)
2 run the install.bat
3.Connect the camera. Computer will find the camera and install this new driver
4.After camera driver installed success. Uncompress the VIDPID.rar and following the step of the .doc
5.After successful rebuild. You can install the formal driver of QHY5. See if it works
6.After it works. You can add a write protect following the PDF file.
For other VID:PID. Please do it as similar method.
Links for the files are as follows
driver.rar VIDPID.rar QHY5 EEPROM Write Protection.pdf The steps are quiet straightfoward if you have done it before. Please feel free to ask here if you faced the same problem, and I will help sedaya mungkin.
Hope this helps.
