Prolific based USB->Serial 8192 baud support
Here is a registry file that should enable 8192 baud on generic prolific chipset usb->serial adaptors. Import the key in to the registry and restart your pc for the driver to pick up the new rate. Thanks to Malser for reporting this was possible, and how.

These options universal. I worked in many programs on speed 8192, and also on speeds 10400, 10472 (https://pcmhacking.net/forums/viewtopi ... 0&start=90). I made tests on 5 chipset of PL 2303 (H, HX, X, HXD chip version) and only one did not begin to work. That which without letters after 2303
Learn sets the speed by using the monitoring program requests to COM-ports, for example «Free Serial Port Monitor» of company «HDD Software». To do this:
• before the opening of a diagnostic run-monitor mode of the monitor port and choose the COM-port, which is used diagnostic program;
• select the presentation, which shows all the requests and responses from the driver COM-port (for example, "Table");
• Open a diagnostic program and try to briefly connect;
• return to the monitor ports;
• found in the log exchange request «Set baud rate» and transfer data rate from the field "Data" from hexadecimal to decimal format. Note that the first is the low byte value of the velocity:
See picture
Data: 00 20 00 00.
The velocity in hexadecimal: 00 00 20 00.
In decimal representation - 8192.

Re: Prolific based USB->Serial 8192 baud support
mine is a PL2303 but it shows up as "usb/serial USB-HID -> Com Device (com9)"
the drivers listed are windows\system32\drivers\hidusb.sys (and others in the same folder)

For me a device is determined so: Prolific USB-to-Serial Comm Port (COM1)
C:\WINDOWS\system32\drivers\ser2pl.sys
USB\VID_067B&PID_2303

How to detect a device in a system with a new driver? Prolific USB-to-Serial Comm Port? How it works on standard rates?

Re: Prolific based USB->Serial 8192 baud support
ive seen bad generic non microsoft certified HID device drivers cause all kinds of pain before. The ones I had were taking over my usb mouse. This was a long time ago and I dont recall the details but I had to do some registry hacking and file deleting to make them go away. After that my mouse was fine again, without it my mouse would not use any other drivers. You might have picked up some similar drivers along the way.
