Hi, I’m new to QuadStick and I have a QuadStick Singleton. I’m having trouble adding/downloading profiles through QMP.
When I first got it, I plugged the Singleton into my PC by USB, downloaded QuadStick Manager, and tried to add/download a profile to the QuadStick. However, it keeps failing with this error:
Error in csv_files_dropped: AttributeError("'NoneType' object has no attribute 'write_qs_file'")
I’ve attached screenshots showing the error and my QMP settings/log.
QMP also says:
QuadStick flash drive not found.
QuadStick Game Controller interface successfully opened.
QuadStick is in PS4 mode.
The Singleton itself still works as a mouse, so the PC is detecting it, but the “In QuadStick” file list is empty and I can’t seem to write profiles onto it. I also checked File Explorer → This PC, and no QuadStick/removable drive appears.
I looked through the forum and found a similar issue where “flash drive not found” + “controller interface successfully opened” suggested the internal flash/config storage might be corrupted or not being exposed. The suggested reset instructions I found were for the FPS/original models, but I have a Singleton, so I’m not sure what the correct reset method is.
My questions are:
I’m very new to this, so step-by-step instructions would really help. Many thanks

Hi, thanks again for your help earlier — I’ve made good progress since then.
I just had a quick follow-up question about profiles. Right now I have three on my Singleton:
If I want the Singleton to start in the WASD profile every time I plug it in, is the correct approach to rename wasd.csv to default.csv?
And if so, should I first rename the current default.csv (No Flash) to something like noflash.csv so I can still access it later if needed?
Thanks again for all the help — really appreciate it.
