Slow USB 2.0 file transfers rx3715

Hi,
I?ve just got an HP ipaq rx3715, and yesterday I transfered a 60Mb file to it over a USB 2.0 and it took about 50 minutes!!

Is this normal? I mean, with my Sandisk flash drive it takes about 30 seconds on the same USB 2.0 interface!!


Thank you.

Unfortunately this is normal. PDAs still use USB 1.1, and more importantly, ActiveSync is quite slow at transfering large amounts of data. Your best bet is to use a card reader to copy large files such as movies and MP3s to the SD card.

Hi,
I am using Windows XP, but I also have Windows 98 SE installed on my machine. One thing that I found curious is that doing the same transfer on Win98 I could get the transfer time down from 50 minutes to about 10 minutes!!

I?ve also noticed that when I transfer files on WinXP, my CPU usage goes to 100%..I?ve tryied upgrading my ActiveSync from 3.7.1 to 3.8, but that didn't make any diffrence.

Do you think there is a way I can get that same transfer performance I get on Win98 on Win XP?

Thank you.

XP should generally be faster, not slower. And the CPU utilization should never go that high! It sounds like something is amiss in your XP install-- maybe a conflicting driver? Also, are you running any anti-virus or firewall software that may be getting overly zealous at checking every byte transfered? If so, you want to setup a firewall exclusion for ActiveSync.
