Copyright Future Technology Devices International Limited 1 FT2232H Dual High Speed USB to Multipurpose UARTFIFO IC Datasheet Version 2. Newer kernels including 2. The driver version string should be no older than June 2. VT6. 20. 2 problems may still remain, especially on 2. Some older Linux distributions ship 2. EHCI code based on. If youre building a distribution, avoid using such old code. EHCI driver are no longer. You should probably know that USB is an abbreviation of. Universal Serial Bus, which is widely used for. Its not universal. Hyper. Transport. PCs typically support one or more USB controllers one per. USB bus each of. USB peripherals. Legacy free PCs omit non USB peripheral support. RS 2. 32 serial lines, and PS2 ports. Partially excepting the new USB 2. OTG support. USB is asymmetric. For example, its cabling is always asymmetric even with OTG. USB supports hotplugging for all its peripherals. USB. Both those features help reduce end user setup and configuration. USB technology. Today, most USB peripherals and hosts support USB version 1. Mbitsec. and full speed at 1. Mbitsec. USB 2. 0 is appearing in current product designs, and one of its. Mbitsec. To put it another way USB 1. OK for low speed devices. Ethernet 1. 0 Mbitsec adapters, or consumer electronics gadgets. MP3 players. USB 2. USB 1. 1. You need USB 2. PC peripherals like. MP3 jukeboxes or. USB video, or. get concurrent use from a bunch of 1. Base. T networking adapters. OK, its faster. Linux user notice about USB 2. Well go from the outside in starting from what youll. Linux user mode tools. More technical details are in later sections. One thing you wont notice is designed in compatibility problems. Apart from some constraints on how you set up high speed devices. USB 1. 1 hardware works just fine with USB 2. Updated USB Logos One thing that you should watch for, and use to your. Earlier USB peripherals sometimes had compatibility problems, and the. USB 2. 0 could have. Instead, there are new USB 2. That is, this isnt purely a marketing gimmick, theres. Here are the new and old USB logos Be cautious about high speed peripherals that for any reason. Those devices may not work very well, and itll be your fault for. Hubs and Cabling One big win for the USB 2. With the possible exception of some low quality cables. USB 1. 1 very well, you can keep using. USB cables. There was no need to switch to optical. There are new Mini B cables, that can help eliminate the need. USB peripherals. Think of a camera, cell phone, or PDA classic B sockets take. However, some people report they need to avoid using long. USB cables. If youre using long cables and having problems. USB 2. 0 hubs are special. Not only do they support high speed devices older USB 1. USB bandwidth. See the later section on backwards compatibility for information about. USB On The Go OTGThere is also a supplement to USB 2. USB On The Go. USB devices that are often used without a PC host. Few end user OTG products exist yet newer embedded Linux. OTG relies heavily on those new USB Mini connectors. It also defines a modified USB 2. The key change in OTG is defining a new Dual Role type of peripheral. USB host when you connect it to another peripheral. Most OTG capable peripherals will have special Mini AB sockets. Because of how the USB mini plugs and jacks work. Mini AB sockets accept either the. Mini B peripheral jack at one end of a USB cable. OTG. Mini A host jack at its other end. Use the peripheral end, and they start out as a peripheral. Use the host end, and they start out like a USB host. PDA. or swap songs with your friends MP3 player. If you connect two different dual role devices, the wrong one may. In that case, the optional OTG Host Negotiation Protocol HNP. Host Controllers and Backwards Compatibility. You can connect USB 2. USB 1. 1 hosts and hubs. Mbitsec, not. at 4. Mbitsec. To get high speed behavior youll need an updated host controller. It must support USB 2. EHCI standard. Today you can get those as PCI cards, usually with a three or five port. NEC, or sometimes a four port one from Philips or VIA. More importantly, essentially all current generation PC motherboard silicon. Bmw Maintenance Program Exclusions more. EHCI controller built in. Linux users have reported success on most of these, with. ALI, Intel, NVidia, Si. S, VIA, and others. Thats in alphabetical order Im not intending to slight any vendors. See the section on Linux support later for more specific information. You may also need newer hubs with USB 2. Probably the most important aspect of such hubs is how they. The short version of the story is that to get high. EHCI controller thats using an EHCI driver. USB 2. 0 hubs. That is, a tree of USB devices can start out with a high speed. USB 1. 1 hubs to that tree. USB devices on branches below that hub will only operate at. USB 1. 1 speeds. USB 2. For now the lesson is that if you want to use a device. You can do this with usbfs. Beyond those general issues, Linux users will notice a. You may know usbfs through its original, and somewhat. The name changed because it. If you use usbfs perhaps through scripts like usbtree or. Most notably, the USB version for some devices will be 2. Mbs when. theyre running at high speed. In compatibility mode, at full speed, theyll say 1. Mbs. Heres what usbtree. USB 2. 0 controller.
