First device (no other devices plugged in) dmesg output
[10095.896200] usb 2-1: new full speed USB device using uhci_hcd and address
4
[10096.073705] usb 2-1: configuration #1 chosen from 1 choice
[10096.216333] rndis_host 2-1:1.0: RNDIS_MSG_QUERY(0x00010202) failed, -47
[10096.223042] eth1: register 'rndis_host' at usb-0000:00:1a.1-1, RNDIS
device, 80:00:60:0f:e8:00
ifconfig now detects eth1 and synce-pls -p DEVICE_ID works.
After connecting the second device, dmesg output:
[10284.568072] usb 6-1: new full speed USB device using uhci_hcd and address
6
[10284.739528] usb 6-1: configuration #1 chosen from 1 choice
[10284.846093] rndis_host 6-1:1.0: RNDIS_MSG_QUERY(0x00010202) failed, -47
[10284.853772] eth2: register 'rndis_host' at usb-0000:00:1d.2-1, RNDIS
device, 80:00:60:0f:e8:00
Which is basically identical to the output when the first device is
connected, but eth2 doesn't exist according to ifconfig.
synce-pls -p DEVICE_ID still works but synce-pls -p DEVICE_ID2 can't find
the configuration.
iptables -a didn't do anything (iptables v1.4.0). Perhaps you mean iptables
-L? The output of that is:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
the output of ifconfig is:

Any idea how I can spoof the mac address on my phone? Or is my phone's
hardware even specifying this address (seems unlikely to me since I also
have an HTC 3125 that just happens to use this HWAddr)? If synce is
specifying this address, can I change that somehow? Googling
80:00:60:0f:e8:00 seems to reveal that it is the common HWaddr for RNDIS
sync even in Windows.
An alternative solution to this problem would be getting the blackjacks to
run in ppp mode. This works fine with all the other phones, and is only a
problem with the blackjack because it seems forced to run in rndis. As
mentioned before I've already tried specifying manually to use ppp mode by
modifying the registry and I have also tried using an app I found called
USBSwitch.cab that is supposed to switch between RNDIS and PPP on phones
that don't offer the functionality in the GUI. However, neither of these
options allowed my device to be detected at all by synce (and I think
USBSwitch.cab fails outright on the Blackjack)
