message: The model for USB OTG needs to be more clearly explained.
Firewire/IEEE 1394 already does this, so the benefit over using
another high-speed interconnect should be explained.

:The benefit is the same benefit you get from adding USB host capabilities to any device in a class where its competitors are already USB devices - The ability to turn its USB port into a dual-purpose jack that can manipulate a ridiculous number of peripherals. It's about cost and minimizing the number of different buses required on an embedded device. The article would certainly benefit from clear articles in the text, but devices like a Chumby, game console, or PDA, all have fairly obvious business cases. MrZaiustalk 12:50, 9 August 2009 (UTC)
replies: text: Generally; can only the factory turn a USB port into OTG dual-purpose jack?  Generally a software/firmware update could not? Seems this should be emphasized in the article. I'm surprised OTG specs are so rarely given for tablets etc. One suspects from the specs/reviews that most microUSB ports are only for charging, not memory expansion etc.  — Preceding unsigned comment added by 71.138.23.59 (talk) 22:22, 16 February 2014 (UTC)
thread_title:  Business case? 

message: What really needs to be more clearly defined is whether or not all devices with this functionality follow this spec. Is this used by the Nokia Internet Tablets, or is there something more to it? Seems to be, given the Duck comment above, but it warrants confirmation. It's been two weeks shy of a year, but the article still doesn't list a single concrete device that implements this specification. Cleanup still badly needed, as well - The circular and highly technical language in the lower sections could be reorganized effectively, but is dense enough that I'm reluctant to touch it without more subject knowledge expertise.

thread_title: Some older Nokia s40 support on the go?

message: There appears to be a lot of misinformation here- USB OTG (from the specification available on the USB website):
On-The-Go: An OTG product is a portable device that uses a single Micro-AB receptacle (and no
other USB receptacles) to operate at times as a USB Targeted Host and at times as a USB
peripheral. OTG devices must always operate as a standard peripheral when connected to a
standard USB host.
I believe that all the devices mentioned in this article are actually USB Dual Role devices- which has a very different electrical and protocol specification. While there are is a variety of silicon that supports OTG, I am not aware of any true OTG devices.

thread_title:  The BeagleBoard uses USB-OTG 

message: I had originally called this "Lead section too technical," but then I expanded it, mostly by copying from down below, so now it just needs work...corrections, clarifications & what not. I intentionally made the lead a bit redundant due to the topic's complexity. Yet now it may (or not) be too redundant down below.  Here's my original post: 
A 4-paragraph lead section should be understandable to the average person, see Wikipedia:Manual of Style (lead section).  The lead section says: 
USB On-The-Go, often abbreviated USB OTG or just OTG, is a specification that allows USB devices such as digital audio players or mobile phones to act as a host, allowing other USB devices like a USB flash drive, digital camera, mouse, or keyboard to be attached to them. Unlike conventional USB systems, USB OTG systems can drop the hosting role and act as normal USB devices when attached to another host. ....  Obviously one can't have a gut understanding of what OTG is and does unless one has a gut understanding of what a host is. Before I read that I thought I had a semi-workable idea what those things and relationships were. 
My vague impression is that a host is rather ephemeral, subtle, and changeable. IOW, difficult to explain. I wonder if some contrasting examples in the article might help? For example, not every device with a USB connector can use a USB thumb drive? Does a camera or tablet with USB OTG need file management software to use a thumb drive? Is that software/firmware part of the OTG definition?
Example: some tablets brag that they use USB OTG, therefore a thumbdrive can expand memory, which seems to imply that regular USB connections will not. Explaining this might clarify the definition/relationships between these devices.  Similarities and contrasting differences being highlighted perhaps.
Most readers never read beyond the lead section.  I notice the next section is called: Architecture, which implies jargon-laden & too-technical, but it's actually written very well!  Suggest giving a lay def to "bus" and renaming that section to "Overview" to encourage reading. However, because that section is so extraordinary, is not a reason for a weak Lead.  I may copy 1 1/2 paragraphs to the lead to make wiki guidlines & the "Lead-onlies" more happy, but that will be incomplete, redundant, & a rewrite would be FAR better. (But some redundancy is a good communication tool.) <Br> --71.138.23.59 (talk) 22:04, 16 February 2014 (UTC)

I'm still befuddled as to why that practice seems to be so extensive among sellers and manufacturers. ...Reviewers too. It seems to be like selling gold stuff, but forgetting to mention it's made of gold. My quandary is that goes against "simple economics," an impossibility.  My only explanation is that USB OTG is not as valuable as this article implies.  ...like perhaps the same goals can be achieved without USB OTG? ...Or some are bragging where they aught not?  ...or...?   ...Thoughts? <Br> --71.133.254.31 (talk) 16:48, 26 February 2014 (UTC)

message: Please add a section about USB OTG Flash Drives. They seem to have two connectors. Are they backward compatible with traditional USB socket storage uses? What additional features do they have?-96.233.19.191 (talk) 16:35, 9 July 2014 (UTC)
replies: text: As best I can see, these devices are slave-only on both ports, so OTG is something of an advertiser's misnomer when applied to the flash drive. It's just that they can connect to a USB-OTG port on, e.g., an Android 4+ device by a micro-USB connector, which then acts as the master to the flash drive's slave, although mobile phones usually operate in slave mode.

thread_title:  New to editing stuff here  

message: This article needs to be updated to reflect the universal introduction of USB Type-C, as well as other ports like Lightning which are technically also OTG. It is very heavily reliant of micro-B right now. I've done some work, but there's still a few sections that only mention micro-B and USB-A. JaredTamana (talk) 13:48, 23 April 2018 (UTC)
thread_title:  Introduction of Type-C 

message: This article only specified two types of OTG cable: male mini-A to male mini-B, and make micro-A to male micro-B. However, I think the more well-known kind of OTG cable is the male micro-B to female USB-A one, which is probably out of spec, though I'm not sure. Maybe this article should be updated with information related to such kind of cable. --Wzx1996 (talk) 15:45, 17 November 2018 (UTC)

message: The USB specification never calls its nodes master or slave, it always talks about Hosts and Devices - which can be further divided into Hubs and Functions. Using the terms master and slave may therefore be unnecessary here. Oskar456 (talk) 07:30, 28 August 2020 (UTC)
replies: text: I'm not sure if it's due to the original terminology change edit or a later one, but the current version of the article now includes the meaningless and confusing term "device device" four times.
