Hi Gorky,
Dear member of SanDisk Community, welcome.
Please, try the following:
- Insert in Image Mate All-in-One a card, and then plug in another port of the PC, and see what happens.
- Try Image Mate All-in-One with a card in another PC, and see what happens.
- Try Image Mate All-in-One with a card in a laptop, and see what happens.
Luck, and then you tell us, what happened, please.
