hi all: when I plug 3g modem dongle to ehci port, it works But when I plug in xhci port, it cannot successfully doing the modem mode change. The related 3G modem driver should be independent by host type, right? Below is my host environment and I also attach log about plug in xhci and ehci. ( as you can see in ehci log, the 3g modem can change to modem mode successfully) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) (prog-if 30 [XHCI]) Subsystem: Lenovo Device 21f7 Flags: bus master, medium devsel, latency 0, IRQ 40 Memory at f2600000 (64-bit, non-prefetchable) [size=64K] Capabilities: <access denied> Kernel driver in use: xhci_hcd
