Hello,

What is the input voltage for the Onion Omega without the dock? I found 3.3 volts listed somewhere. Is there a safe upper limit or range for the input voltage? Such as 3.3v - 5v?

I want to build my own power supply and bypass the dock.

Thanks!

@Zheng-Han Thanks! I have cron set to run the script every 15 minutes. It creates 7 differently named access points all at the same time. Total execution time of the script is about 3.4 seconds.

Here's a screenshot from an Android phone showing nearby WiFi access points.

I purchased the Onion Omega a year ago. The USB has never worked. I have recently upgraded the firmware, and the USB still does not work.

I cannot mount any USB device. None of my cameras or USB storage works. I have at least 6 different types of USB drives I have tested with, none of them work with the omega.. I do not have this problem with any other Linux machines at my house. Two Raspberry Pis and a Debian box have no issues working with my USB devices.

Did I get a faulty unit? See my previous post for pictures of the board, and the original series of posts about this issue from a year ago.

Thanks!

Sorry for the late reply. I finally got around to taking a few pictures of the board.

I'm still having the same issue, and the Omega is running on the latest firmware.

I did notice one pin on the header was left unsoldered, there doesn't seem to be a trace going there though. I tried to add some solder there, but there isn't a pad for it to adhere to. Still the same errors after attempting, and after a fresh factory reset too.

Hi @Boken-Lin,

I've upgrade the firmware to b236 and did a factory reset with /usr/sbin/factory-reset -f. Still getting the same error -71.

Here's the output from USB Serial connected with Putty..

http://pastebin.com/VsVRj8zb

@Boken-Lin - I've used the drives on all of my systems besides the Android Phone. They are formatted with FAT.

I have Ubuntu running as chroot on my Chromebook. Here's the output from dmesg when connecting a USB drive to the Chromebook's Debian (Jessie) chroot.

@Boken-Lin -- Yes, it is! I'm SSH'ing in from different SSH clients on ChromeOS (Toshiba Chromebook 2), Windows 7 (Putty), and an Android phone (ConnectBot). I also get the same errors when connected via USB Serial with Putty on Windows 7.

@Boken-Lin -- Sorry for the delayed reply.. I removed the USB, ran the previous command, re-inserted the USB drive, and ran dmesg. The same "read/64, error -71" error shows up.

Edit: I noticed the new firmware version b234. I ran oupgrade -force to bring the Omega up-to-date from b233.

I ran the previous command (echo Y > cat /sys/module/usbcore/parameters/old_scheme_first) again, re-inserted the USB drive, and dmesg shows the same -71 error.

Hi @Boken-Lin.. I tried that an received the error "write error: No such device".

I tried the same command in other USB related areas and didn't really make any progress. I don't know if it will help any, but here's 1,117 lines copied from my last terminal session. Taking shots in the dark for the most part..

Here's the output of a few other commands..
