Two external drive pluget same time not work

Hello.

Sorry if theme like this already existing in forum. I not finding in search.

My OS Win 7 Ultimate. I have two External drivers. One is Seagate and other is Samsung. When i plug in one, windows find and show to me him. When i plug in second, i get message witch you see in image. Both external work. I plug both in different usb holes in my PC. If i plug one or other first, that first work, but not second. I have same Samsung external drivers and if i plug they both work's. So where can be problem? How to FIX it that i can use both same time.

Are these drives in an enclosure? If so, are both enclosures from the same manufacturer? I would suspect the drivers being installed from the enclosure is the issue and one driver is incompatible with the other. I would try using a different enclosure for one of the drives.

maybe a power problem(?) do both drives have their own powersupply? Or do they use power from usbport?

Strollin, if i understand correctly about that word: enclosure so yes. Both External in Boxes. Models - Seagate Desktop External Drive and Samsung S2 Portable. And there is no problem with Drivers installation because both they work great if i plug only one and not plug second same time.

Kaktussoft, Seagate with power and Samsung get power from USB. But i write this as example. If i use 2 USB keys, different models, so problem that same. One works, but second SAME TIME not.

I'm suggesting the problem my be that the drivers from one enclosure are not compatible with the drivers for the other enclosure which is why they work separately but not when both plugged in at the same time. That's why I suggested trying one in a different enclosure.
