I've got a 1 and 2 gig san disk memory stick duo pro.
Transfer speed via usb2 are really slow!
For example, 400 megs can take 20 minutes.
Any idea on how to speed it up?

I never have that problem.. Maybe it's your computer and not the memory sticks.

You're right Don. It's my card reader, it's a usb 1 I think.
Plugging the psp directly to the PC has fast normal usb2 speed.

lol you can buy the usb2.0 card i think ROUND 10-15 BUCK I JUST BROUGHT ONE FOR 10

the data transfer speed should be around 2.2 MB per second. it's probably is your computer

i had the same probably when i got a newer computer it solved everything, your usb drive is out of date you have to update the software and or buy a new computer.

i suggest updating it first for buying a brand new pc will cost you a big hole in your pocket but if you can afford it and would like to fix your usb problem more power to ya

The bigger cards seem to transfer slower.

My 4GB seems a lot slower than my 2GB one.

Or have I got a dud?

itz ur computer...mine has the same prob but i rather wait than buyin a new pc..old com transfer slow....or how abt using ur frens pc...i think 4gig n 2 gig has the same speed..visit the toilet while transfering huge files...

I hate to think what you are talking about...

mine transfers incredibly fast

sorry man..or u can juz watch tv or have a snack..tat will take ur mind off of waiting so long..have u tried using windows xp? cz im using windows 98...i dont know if i makes any diff to the transfer speed...

I never had that problem man sorry.

Stalksy, thats a good one

you guys should read his post. he already said it was his mem card reader that is usb v1.0 which is slower than the psp's usb v2.0.

also it might be that you have a fake memory stick

I have a windows98 and transfering stuff to my psp takes forever, but at least it works! At first my 1GB wouldn't work and it was pissing me off, everytime I tryed to put a video on it, the whole screen would go black then a message (Unable to write to disk F Error 00000-00000) Then all I did was format my mem stick 3 times through the psp and HOORAY!!! It finally worked!!!!

mines a 1.0 takes bloddy 20mins for a 600mb file!!!

i need one of these, im stuck with a gay 256mb card... but it is bright orange!

400mbs for me is about 3 minutes... its got to be your computer.. i have a 2 gig sandisk

also make sure that u dont have any unnecessary programs running that slow ur cpu down

I have a similar problem, when I plug my psp in. My computer says, a high speed device in plugged into a non high speed port. Anyone know where I can get updates or something to speed it up???

i think its your computer mine goes a little bit faster like 300mb per 10 mins

Yea i think it's your computer.

yea its ur computer...maybe u should update ur RAM

There are USB 2.0 drives you can buy for your pc and he plus right into the pci slots
