CM7 V7 USB Storage will not connect

I am using cm7 V7 ( 4/10/2011) with a Macbook Air running 10.6.7
Running Netarachy 1.3.0.2 BFS+
I can not connect the USB storage to the computer.
When I connect the USB cable to the computer and select turn on USB storage. It says USB storage in use but the Phone never shows up as a Portable hardrive. Sometimes on the phone the screen will flash and it will automatically turn off the USB storage screen. Go from the orange android dude to the green one.
I have tried restarting the computer and the phone several times. No Luck
Any suggestions to a fix ?
I had this problem with my 15" macbookpro. I was using cm7 nightly #26.
I tried a different usb cable & port, & wiped cache on my phone. That worked for me.

[Q] USB Mount or Mass Storage not working on MT4G

The probem:
USB Mass Storage not working in Recovery. I tried everything, reflashing different recovery but its not working, it doesn't give an error message. When card is not inside however it does complain. SdCard is fine because I can flash zips that are on it. Tested on both windows and ubuntu. tried another card as well
USB Mount doesn't work in CM7.2 or any rom or nand restore i've done recently. I had Insomnia at some point, then inferno, then cm 7.1, none of these restores work. Again here no errors, I do not even see the sign for usb detection. usb debugging is enabled/disabled no difference. phone however still charges though.
I'm on a trip right now, but I've not had the chance yet to get another usb cable but the two I have dont work.

He has tried two cables, so I would tend to lean toward the port.

i am in the same boat. looks like my charging port is bad. anyway to replace the charging port? i am not good with soldering
it's not ur usb port
it's htc.. htc devices doesn't support usb host feature.
If you have a rom and kernal that do support usb host then try powering the usb as the htc devices do not provide power out.. use usb Y cable

What? He isn't trying to host the connection. He is trying to use his phone as a USB mass storage device.
Where did you get USB host from in his questions?

Hi all,
I am having the same problem, except perhaps with a different cause. My user account on Windows 7 became corrupt and I can no longer log in, so I had to create a new one.
On the new account, my myTouch 4G is not recognized for mass storage/disk drive mode via USB. The USB cable does work, the port is okay, and I've used both with other devices. The myTouch shows as charging when connected to the computer. I have uninstalled and reinstalled all of the myTouch drivers, restarted computer and phone, to no avail.
When it is connected in USB, it shows as generic "Drive F" and is inaccessible. When I check properties it says mytouch4g. When I check "Devices" it is recognized as portable storage. I have tried with USB debugging on and off, and have set "connected to computer" mode to disk drive.
Any thoughts? I thought possibly loading the generic ADB driver again might help, but I cannot get to the stage where I can force it to load that driver instead of the HTC one.

Windows 7 don't see my G2

Today tried with usb otg cable.
Connect the usb otg to my phone with a usb stick fat32 format. I can't select usb otg in mount.
Tried it with a external harddrive with own power supplies and format as fat 32. Same problem, not possible to select usb otg in mount.
Tried usb otg cable with usb stick with other G2 with same TWRP amd everything work.
It seems the usb otg cable and usb stick are alright. The problem is my phone.
Is it really dead now?

USB OTG not working

Hi,
USB OTG on my Verizon Droid Turbo 2 with Android 6.0 is not working with any USB device I've tried including mouse, keyboard, or thumb drive. The DT2 doesn't respond nor even appear to supply power to any of the devices I attach.
The DT2 Micro-USB otherwise works for charging and connecting to my PC. I've tried multiple cables listed on Amazon as "(10-Pack) BuyCheapCables 6" Micro-USB OTG (On The Go) to USB 2.0 Adapter Cable" that have worked well for me in the past.
I ran the app USB OTG Checker from Google Play with USB OTG System Result = "Your Device OS has USB OTG API !" and USB OTG Signal Result = "System NOT Detect USB OTG Signal"
Frustratingly, youtube videos seem to show OTG success in similar scenarios. So, please any advice would be appreciated...
I'm having a related problem. Otg-usb works when phone is booted normally but when in recovery with TWRP 2.8.7.1 I try to back up my device, I see otg-usb, but can not select it as the target destination. It is formatted Fat32. I try to reformat it in TWRP and it can't write to the media. Get an error to that effect. Note5 MOAR Rom 5.1.

My issue seems hardware related in that any USB device I try to connect gets no response or power from the phone.
I spoke to a few sources on this and most helpfully went to my local VZ and tried on another DT2. Looks to have worked and I'm hoping the new DT2 they're sending me will solve it. A Samsung S7 also worked.
