Does PlayStation 2 slimline have USB 2.0 ports?
I know the classic (fat) PlayStation 2 has two USB 1.1 ports.
Has Sony upgraded slimlines' USB ports (in particular SCPH-90004) to 2.0?
Solution 1:
Wikipedia has a page indicating that the Slimline had two USB 1.1 ports, like all other models of the PS2.
An additional Wikipedia source about the technical specifications for the PS2 can be found here, which also states they are USB 1.1:
USB 1.1 ports with an OHCI-compatible controller
