Cracked phone screen, need to enable USB debugging, but adb won't work in recovery. topic

Hey guys-

I've been searching for hours to figure this out. I cracked my phone screen and I didn't have USB debugging enabled. I'm using a mac on yosemite.

I should just be able to go into recovery and follow the instructions in this blog post to enable usb debugging, so I can reboot into regular android and connect a bluetooth mouse using

HTML Code:

---

input tap

through adb.

But for some reason, adb will not recognize my phone in recovery. I'm using CWM. I cd from terminal into a my platform-tools folder.

HTML Code:

---

abd kill-server

---

, connect my phone,

HTML Code:

---

adb deivices

---

, and nothing. Reboot my phone and try again, and nothing. I can't do a thing with my phone unless I can get access to adb in some way shape or form.

Has anyone else had this problem? Can anyone help? Thanks.
