There must be something else wrong The DS supports aimplement in software. The single-channel versionDSthe duration of the active pullup is fixed on the DS If this is not sufficient i guess i would need datashet choke coil instead which is larger than the whole circuit itself: There are fuse deratings to calculate the neccessary current for a given time.

But this makes no improvement which would surprised me. Probably the usb port of the hub is less picky with some electrical parameters than the notebook itself?
