Need to set up a USB flash drive so it can be read by two different computers

One computer is Windows XP SP3.  As soon as I finish getting things rigged up, it is going offline.  The other computer has Windows 7.  I'm setting things up so that with a KVS switch, I can view either the XP computer or the Windows 7 computer on my monitor.  Only one at a time, not both.

 

Now, my printer will not run on Windows 7, and so when I store files that I want to print, I need to store them to a USB flash drive.  I really don't want to keep unplugging that drive from one computer box to the other.  I'd like to keep it plugged into one thing.

 

So, I would like to know if there is a device I could plug the USB flash drive into that I could run a cable to from the XP box and another cable to the Windows 7 box so that either computer could read or write to the drive, but not at the same time.  So, if I switch to the Windows 7 computer with the KVS switch, I'd like to flip a switch that will switch the USB flash drive to read and write from the Windows 7 computer; and conversely, when I switch to the XP computer, I'd like to flip a switch so that the USB flash drive would now be read and written to by the XP computer.  The device would automatically "unplug and plug in" the device from one computer to the other but do so electronically rather than physically.

 

Is there such a device?

Don't know if this is what you have in mind, but I might try doing it with permissions, or mapping/unmapping the flash drive over the network.

 

If the "XP flash drive user" is not logged on, it can't access the drive.

 

If the "Win7 flash drive user" is logged on, then the "XP flash drive user" needs to be logged off and vice versa.

 

Or you might write log on and log off scrips to map and unmap the drive on each machine.

 

My 2 cents.

Also, if I might ask, why not network the two computers (which I actually presume you have) and store whatever it is you need to access from either in the Public folders?

 

I can access these on each and every one of the machines on my home network.  If it must be USB you could leave it plugged in on one machine and share the drive on the LAN.

I'd probably go with the I/O Gear product linked by JohnC_21 as the other two seem to be geared for printers and scanners.  I've never used a USB switch for a memory stick.

 

One thing you will have to be careful about is ejecting the device, or making sure that the write is finished, before you switch machines.

 

Something like this cable, might be an option to connect the two computers together and allow you to put files on the other machine.

Thank you for the suggestions everyone.

I don't want to network the two computers.  It doesn't make sense to me to do so.  I suspect if I did, that would make the XP box vulnerable to the internet via the Windows 7 box and the shared stuff.  I don't want to take chance once I get the bugger off-line.  I have only one monitor.  The two computer boxes are going to be right next to each other.  How on earth would one "Map a drive" anyway?

 

The link to the IO Gear switch got me to exploring, and I discovered this one:

 

https://www.amazon.com/SIIG-SuperSpeed-Switch-Adapter-JU-SW0012-S1/dp/B005EHND30

 

It specifically states that it will work with USB external drives, so that indicates to me that it will work for a flash drive as well.

Mapping a drive would require the machines to be networked...

I've been doing some reading and looking around, and here's my thought of what I can do given the warnings I've read about switching while the USB flash drive is still being read or written to.

 

I can have the drive plugged into the switch.  When I wish to switch from one computer to the other, I can go through the computer interface and turn off that drive.  Electronically unmount it.  I do that anyway when I want to physically unplug it.  Alternately, I could power down the computer. Then, I flip the KVM and USB switches, then turn on the other computer.  The computer SHOULD then mount the USB drive that's plugged into the switch.
