CM12 rumrunner adb error?

Hello everyone!

Here's the short version:
I want to s-off my htc one xl using rumrunner. However, every time I run the sudo ./sujo (linux) script, I always get the same error:

Code:

---

ERROR: run rumrunner again and READ (no adb connection to device.  Debugging on?  Drivers?)

---

I have checked my fastboot and adb connections and they all work fine. I have also enabled root permissions for adb and applications, usb debugging and the 'adb over network' options in the 'developer options' menu of CM12.

Here is a more detailed step-by-step of what I do:
First, I check the adb connection with "adb devices": (I've also tried other commands, just to make sure everything's OK)

Code:

---

:~/Android/rumrunner_HTC_0.5.0$ adb devices
List of devices attached
HT248W301724        device

---

Second, I run the "soju" program in the rumrunner download file:

Code:

---

:~/Android/rumrunner_HTC_0.5.0$ sudo ./soju

I tried running the rumrunner script before flashing CM (i.e. while I was still using the stock HTC rom) and it worked all the way up to the "your phone is not rooted" part, at which time I flashed TWRP recovery onto my phone and flashed straight into CM (figuring it wouldn't make much of a difference).

I don't really want to get into the whole RUU mess. Anyone know what's going on here? How do I fix this adb issue? Help? :)
