Flash Drive USB Compatibility

I recently purchased a new Dell E510 and want to move files from my old Dell XPS T450 to the E510. I purchased a SanDisk Cruzer Mini USB flash drive for this purpose. The literature that came with the flash drive says it's backward compatible to USB1.1. When I slide the flash drive into a USB slot of the T450 and bring up My Computer, the system sees the SanDisk drive. But when I try to send a file to that drive, it doesn't show up as an option on the Send To menu. I am wondering if I have USB1.0 on the old Dell. When I check the release history of USB I see that 1.1 was released in Sept of 1998. My old Dell was built in May of 1999. So it seems possible, at least, that I have 1.1. Is there some way to check this? When I look at the hardware list for the T450 it says I have an Intel 82371 AB/EB PCI to USB Universal Host Controller. Does that indicate the USB level? Also, I thought all USB levels are backward compatible so even if I have 1.0 it should work (however slowly) with the flash drive.

Is this USB issue the reason I can't save off my old files? If not, what do I need to do move files from the old system to the new one.

Welcome to Windrivers BikerBill.

If you see the drive when you go to My Computer and open it in a window, why not just drag the files that way? It my just not show up in Send To.

Adding a send to to a removable device is not generally done, but if you really want one, here is how to do it most people just drag and drop on the disk icon

What operating systems are you using on those machines?

If you see the Sandisk cruiser in my computer then USB 1.1 makes no difference at all other then its a little slower.
Moving the files is a matter of copy paste.
Copy them where they are and then paste them in the Sandisk.
