Dont know what to say. The item has no numbers or names on package from Hong Kong? On the unit is USB TO PS/2 and 501667-001 and HC SD
Item number of 1 that looks like mine is 220237420309.
I did find 1 linux that didnt like it out of 16 linux I have? XPE on my S90 likes it, the 3150SE I dont use USB key or mouse.
I took a chance and it worked, no guarntee?
