Sep 17 00:41:47 <adapted> Hi. I just got my plug, and straight away I have a problem with a USB drive. I have a 2.5" drive in an unpowered USB enclosure (I read a forum post from someone claiming that this setup worked for him). If I connect it directly, the drive powers up and spins, but it is not recognized either by uboot or the linux usb stack.
Sep 17 00:41:54 <adapted> If instead I connect a powered USB hub to the plug (which is recognized) and then connect the drive to that, then I can hear the drive power cycling repeatedly, and it still isn't recognized. By not recognized, I mean that either it doesn't show up at all, or it shows up but I get a "can't set config #1, error -71" message.
Sep 17 00:42:30 <adapted> Has anyone else experienced this, or been able to fix it?
Sep 17 00:43:27 <robbat2|na> adapted, can you see if it works with a different device and that same hub?
Sep 17 00:43:44 <adapted> it certainly works with my PC with no hub
Sep 17 00:43:53 <robbat2|na> i mean plug -> hub -> storage
Sep 17 00:44:09 <robbat2|na> alternatively, please post up the full USB descriptors in a pastebin
Sep 17 00:46:10 <adapted> oh, I see
Sep 17 00:46:38 <adapted> hang on...
Sep 17 01:01:47 <adapted> ...I can connect a non-storage device to the powered hub, and that works...I have 2 different powered hubs from different manufacturers with the same issues...I can connect a powered 3.5" enclosure directly to the plug, or to an unpowered hub, but not to a powered hub.
Sep 17 01:02:01 <adapted> Looks like something's wrong with my USB power adapter
Sep 17 02:05:16 <adapted> Okay, so I checked the output from my USB power adapters - I did have one that was bad, but the other is good (5V, max 5A). Connecting my hub to this and to the plug is fine. When I then connect the 2.5" drive enclosure I'm back to the same problem - either it doesn't show up at all, or it does, but I can't access the drive.
Sep 17 02:07:14 <robbat2|na> adapted, I gotta go out and buy groceries, and then make dinner
Sep 17 02:07:21 <robbat2|na> but with the known good hub and power supply
Sep 17 02:07:26 <robbat2|na> please post the full USB descriptors
Sep 17 02:07:32 <robbat2|na> for all devices in the chain
Sep 17 02:07:55 <robbat2|na> # lsusb -vv
Sep 17 02:07:57 <robbat2|na> to pastebin
Sep 17 02:08:09 <adapted> will do
