+Subject: [PATCH] MLK-9829 usb: core: print suggested message if failed to get
+ device descriptor
+MIME-Version: 1.0

+This is required for USB OTG and EH compliance test 6.7.22(A-UUT “Device No
+Response” for connection timeout). When the connected usb device(PET) does
+not response to transactions, host will fail to get device descriptor.
