A Linux-to-USB-to-PSP problem.
To me it sounds like Linux transfers throught the USB cable, then the PSP takes it and and sticks it to the memory stick.
In theory, Linux IS done transferring the file, but the PSP has yet to utilize it and put it on the memory stick. When you do an unclean unmount, PSP is like WTF am I doing, since it assumes when the cable is removed that it should be ready to play, hence the incomplete file download.
Basically Linux sees it has a 3-way straightforward transferral, while in reality, it is a four-way transferral requiring the PSP to actually install it.
Make me wonder if the PSP has a temporary folder that it keeps somewhere.
Some proof, however credible, in lies in the fact that when you download something from the Playstation Network, that it has to download & install it.
Unless you can find some PSP-Linux protocols somewhere, I'm afraid you may be stuck with watching the blinking light.
Just my opinion, subject of course, to being incorrect.
