Slow transfer speeds to USB 2.0 flash drive

Hi all,

I know that this topic has appeared once or twice in these forums but there haven't been any resolutions and they've been quiet lately so I started a new one. 

Recently, I migrated from Windows XP to 7 and found this problem. When I try to copy a file (a 1.2GB video) to a usb flash drive that I know is usb 2.0 hi-speed (copying files to it in xp were really fast) it takes over 2 minutes. 7 reports that it is copying at 3-4 MB/sec. When I copy from the flash drive to my computer it copies at about 9-10MB/sec. I've also tried plugging it into the rear ports but that doesn't change the transfer speed at all. I know it isn't something related to the flash stick itself because transferring files to it in xp were a lot faster.

Some random information: Transferring files from one hard drive to another averages at about 60MB/sec (both of the hard drives are SATA II drives). I'm not sure what speed it should be but it doesn't feel drastically slower than on my xp machine. Windows 7 and my device drivers are all up-to-date.

System specs:

Dell optiplex GX620

Pentium 4 3.2GHz

2GB Ram

Windows 7 Professional 32-bit

AVG 9 free edition anti-virus

My setup is almost identical to how it was on my windows xp machine except I have less programs installed so there isn't something new that could have caused problems.

    In case anyone else stumbles in here:

    Driver update to increase the maximum USB transfer size in Windows 7 and Windows Server 2008 R2

    "By default, the maximum USB transfer size for USB storage devices is 64 kilobytes (KB). This default setting is configured in the USB port driver (Usbport.sys) in Windows 7 and Windows Server 2008 R2. An update is now available that lets you increase the maximum USB transfer size to as much as 2 megabytes (MB). See the "More Information" section for details about how to do this after you install the update."

    This worked, well, sort of.. video files transferred over much faster (like XP) but right near the end of the transfer progression stops even though it is still processing, still a wait until it finally processes/transfers fully and better than it was before I think.
