Since then there has been at least one patch to improve performance in the= =20 EHCI driver. When the cat command stops, could you try to run: usbconfig -u XXX -a YYY dump_device_desc dump_curr_config_desc On that device. Is usbconfig able to extract the string descriptors in the= =20 device and config descriptor? Or do you get timeouts?

Usually the maximum current is given by the device descriptor, but it might= =20 now be the actual value. See usbconfig dump_device_desc. =2D-HPS
