I'm having a problem setting this up, and I wonder if anyone has some advice.
I successfully set this up (see post #11) with a USB OTG cable and a powered hub. But I wanted to set it up exactly as CaptainMuon suggested, i.e. with the Y-cable. It just came today, and it's not working. As CaptainMuon said in a later post, there are lots of cables out there, good and bad, so who knows if mine is good.
Here is the cable listing on ebay, not that anyone will be able to tell if it's good or not!
I connected everything just as CaptainMuon suggested:
- Y cable power plug (typically red) to the PC or adapter
- Other Y cable plug into the OTG cable
- OTG cable into the phone
- USB device into the Y cable socket
I am connecting to my laptop to get power. The only questionable part was which part of the Y-cable had power...my Y-cable did not have a red plug (male USB A). So I'm using the "skinnier" one, and it must be the right one. I say that because if I try hooking the other male USB plug to my laptop, I am able to see the phone as my E: drive. That tells me that is the data cable.
When I issue "lsusb" before the "echo host" command, there are 2 entries. IThe "echo host" command always adds a 3rd entry. On my successful try (with the USB powered hub instead of the Y-cable), 2 more entries show for the actual device(USB microsd adapter) that I inserted into the hub. But in this unsuccessful try, only the 3 entries show for "lsusb", and the device will not work. I try to mount it with stickmount, but there is no point in that....the fact that no new entries show for the device means the stickmount will not work.
So...I guess this means I have a bad Y-cable. Does someone have a suggestion for a simple way to prove the Y-cable does or doesn't supply power? I mean, something that doesn't involve the phone at all. I hope that isn't too vague!
EDIT: Well, a thumbdrive is working fine with the Y-cable. This is the opposite of what occurred with the USB powered hub. I could get the microsd adapter with a microsd card to work fine. But I could not get a thumbdrive to work. So I'm confused, yet I'm very happy to see that my Y-cable is working fine. So I apologize for the long post!
EDIT2: About a month later, I got another Y-cable. It works well. The Y-cable mentioned above obviously had some capability, but it must have been flawed. The new one allows charging to occur also.
