I’d like to point out something really weird happening on bb xms.
I have a bbXm Rev C and a C1 both using the demo images provided on the elinux.org.
I have a 3G modem that i need to provide an internet connection. The 3G modem board has a ESD protectio chip which we need to remove to make the kernel enumerate the device (bbxm REV C). On the rev c1 I do not need to remove the ESD protection to make the kernel enumerate the device.
I checked on the bb website the changes made from rev c to rev c1. It says: “Only one change was made for this revision. The pads on the expansion headers wee beefed up to address some issues we were seeing where there was a disconnect between the etch and the pads inside the PCBs. The schematic and bill of materials remain the same as revision C.”
I don’t get how this would make any difference (beefing up in consolidating right?)… So I tried to connect the device on another USB port on the REVC1… and it doesn’t get enumerated “hub 1-2:1.0: unable to enumerate USB device on port 5”.
