Hey guys,

I'm having issues using PSPLink to find exploits in PSP games.
I downloaded PSPLink 3.0 and installed it in my GAME folder.I have a phat PSP with 5.50 GEN-D3.Then I moved all the plugins to seplugins folder and I disabled them.

I tried to install LibUSB PSP type B driver but it said that Windows did not find any driver for my PSP.I looked in "System -> Devices -> USB Devices -> Unknown device (Which is my PSP) -> Information" and it says the ID of my PSP was "USB\VID_6472&PID_01c9".I looked at psp.inf file in the driver folder and the ID needed was "USB\VID_054c&PID_01c9".So I changed that to "USB\VID_6472&PID_01c9" and I was able to install the driver.

Now, with all plugins disabled, I launch usbhostfs_pc.exe on my PC, then I run PSPLink 3.0 EBOOT on my PSP, and I launch psphs.exe on the PC.But in usbhostfs_pc.exe, there is only written :

Use Linux, that will solve your Winproblems.

If you want to use it as plugin, you need to add usbhostfs.prx too.

I had the same problem (there was nothing on pspsh). In my case i had psplink's port used/blocked (i still don't know).
Someone gave me this .bat script to run psplink & pspsh on diffrent port which was a solution.

Use the windows port from heimdall just to be sure that you have all the good librairies installed at your pc http://minpspw.sourceforge.net/
in the port you have the full sdk included the psplink and the usb driver
for windows. It use libusb a port of a linux librairie to use usb at ring 3 (user)

I think the problem lies in the wrong USB VID. Probably your idstorage keys are corrupted from downgrading (that you got a TA-082 would point to this, too).

Try using Chilly Willys KeyCleaner v1.4 to fix the keys, restore the driver VID back and try again.

I don't know any official download location, but you could try QJ.

Nope you don't need to place usbhostfs.prx as plugin.
PSPLink already handles the required USB driver related operations by itself.

What Coldbird said, just run the EBOOT and connect a USB cable when usbhostfs_pc and pspsh are up and running.

Thanks again guys..
The problem was actually my TA-082, my ID storage keys were corrupted and I fixed them.Then, I downloaded a version of USBHost made for TA-082 and now PSPLink works perfectely !
I had found a buffer overflow in a game but it won't lead to anything, $ra and $sp seem to contain normal addresses so far.
I have an other problem now, I need to reinstall LibUSB each time I use PSPLink because Windows forgets the driver everytime -.-..
Thanks again !

Just to let you know, some exploits are done without $ra or $sp being corrupted (not at first at least). That's just the most obvious version. Some RE effort should tell you if your vulnerability is exploitable or not.
