Thats all. In Ableton,the setting MIDI input must be set to USB MIDI.

if yes, then you have lap top issues, ONLY.

have you tried a diff. usb cable.
Laptops can not power the hdd via the USB at all, and in fact
should be avoided at all times. no matter.
the laptop can be infected.
the laptop might have USB issues, with drivers.
do a USB driver update. (no 0S stated)
does the HDD show up in Disk manager, as DISK2
can you set the drive letter?
can you set the volume label on this disk via DM?
if yes, you then can read and write the drive.
as stated on all pages for USB
disconnect all other USB devices, and now try this HDD.
do a full virus scan, and malware scan
do wInDoZ update.
I think i hit them all.

For the PSP to charge via USB, it has to have an active connection with your PC or Laptop. In order for that to happen, the PSP has to be on and saying "USB Connect". You'll have to charge it with the standard PSP charger.

Hook up your Sony PSP to your computer via a USB cable. Turn on the PSP and put it in "USB CONNECT " mode (it should display the words "USB CONNECT" on the PSP display during the entire time you're transferring files, and plug it in if you don't have a fully charged battery).

Be more specific with your questions please.

How to Play PSP using the PC Monitor/TV/ETC?

(You need a PSP video out cable. You can find them at a number of retail stores or at GameStop, or the like. You can also order them online as well),

Also, you should use tSony Meda Go software to transfer any files.

....Oh, and one more thing, make sure you include your model number (either PSP 1001, 2001, 3001, or PSP Go),when searching for relavant information about the psp, since each model is different, especially the PSP 3991 & PSP Go models. They used improved copy protection on these newer models.

......Please remember to rate me. Thank You!!!

When you connect the PSP via the USB, does the orange light power on? If you are using the standard USB cable and attached to the top of the PSP, from experience, it needs at least to have a little amount of battery power. If not, it will not totally power on or charge. You need the A/C adapter to charge the battery pack.

I can charge my PSP through USB cable even if its powered off. I'm using this one:

Try reformatting the memory stick. If that does not work he can try to connect just the memory stick it self ( may need an adapter) to the mac and formatting it there. Other wise you may need a driver for the PSP.

okay. here's what you need to remember as i encountered the same issue and had it resolved.

1. connect the psp tv out component cable to the tv. make sure you have every cable in their correct plug-ins.

2. on your tv remote, press output until your tv displays the correct output data info. it will display component 1 or component 2. make sure this aligned with where you connected your component cable.

3. turn on the on the psp, then press and hold the display button ( it is near the start and select buttons on your psp, with a box like icon. after 5 seconds, it will give you a gray screen with a box icon and an arrow which means you are transferring the data out from the psp to your tv display.

4. enjoy your psp on tv!

Try to use a memory stick card reader and connect to your computer instead !!
