Communicates Successfully Every Time

By 

from Undisclosed

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I have hundreds of clients who have equipment with which I occasionally I have to communicate. I use an Apple laptop with the latest OS. Because the client's devices use only PC Windows, I use Parallels to convert to the Windows platform. Then I use the Keyspan serial adapter and a special modem to get the signal onto the phone lines. The Keyspan works every time.

USA-19HS issues, unstable with USB 3.0, hard lockup on resume from standby

By 

from Undisclosed

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

The USA-19HS adapter and/or its driver causes following issues when computer resumes from S3 standby or sleep mode:

1. In case adapter is attached to USB 3.0 port, whether COM port is idle or open, the PC locks up while attempting to resume from standby (the lights turn on, fans start to turn, but there is no video/display). Reboot with reset button or power cycle is required.

2. In case adapter is attached to standard USB 2.0 or USB 1.1 port, the application that had COM port open at the time PC transitioned to sleep mode loses the connection to the port on system resume. The port must be re-opened within application after resume.

The issue with USB 3.0 comes up when using PC with Intel integrated USB 3.0 controller. I have also seen it with Asmedia USB 3.0 controllers, but they have problems of their own. Intel however is stable with everything else I have. Since IntelÕs USB 3.0 controller is present on every new PC, I thought it might be good idea to report the issue. I hope it is going to be resolved in the next USA-19HS driver update.

The only USB 3.0 host controller that USA-19HS does not seem to have stability issues with is one based on NEC/Renesas chips.

My current hardware is Intel Z97 chipset (Asus Z97-E mainboard) and USB 3.0 eXtensible host controller driver version is 3.0.2.54 (10/30/2014) running on Windows 7 64bit. But again, I have seen this issue with older systems that provide USB 3.0 ports. What makes the situation worse is that Z97 seems to route all USB 2.0 ports through new USB 3.0 controller and plugging adapter to USB 2.0 ports still causes PC to lock up on system resume.

The driver for USA-19HS has not really been updated since 2007. At that time there were no USB 3.0 controllers. The new driver installer has been released in 2010 to support Windows 7, but driver itself has not been updated. The driver version number as indicated by device manager, remains the same 3.7.0.5 as in 2007 release.

In my line of work I have been dealing with a lot of USB to serial adapters some purchased directly like USA-19HS, some bundled with other equipment.

The USA-19HS is based on Texas Instruments (TI) USB to UART chipset. The important thing to note is that adapters based on other chipsets do not have any of these problems.

I do like that this adapter continues to be supported on new operating systems and that it does not have issues other adapters have. Some other competing products are purposely, maliciously and automatically disabled by manufacturer for use on newer operating systems. They push new driver through windows update that detects chip version and depending on windows version either allow its use or not. Slightly older 64bit driver allows it on all windows versions (7,8,8.1). This is all in attempt to boost sales of new products with same functionality. I will never buy from the company that does this. It will boost sales of course, but for the competition. Some (two) have counterfeit chip problems and punish unsuspecting end users by pushing new driver through windows update that detects and disables the adapters based on these counterfeit chips. Hey, why litigate evil doers when you can have customers do the scrupulous work of determining whether what they buy is genuine or counterfeit. Again, I do not want to give business to companies that do this to me.

If not for USB 3.0 PC lockup and closed port on resume issues, I would highly recommend this product.

There is also the thing with subpar USB connector that does not snap cable tightly and allows it to slip out way too easily. But that is minor compared to other problems. I think I read some response to review that states supplier of connectors has been changed to resolve this issue.

Thanks.

The industry standard!

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I've been using this USB to serial adaptor for close to 5 years, and I've used others as well, and they're supposed to be compatible.... Don't hold your breath!

This is the one that will work with almost any OS and/or software! I am a 35 year alarm technician and also work with other tech as well. Save your time this is the one for you!

In my field, we still are way behind the time as most of the modems still used for downloading and programming systems are at least 35 years old as well

(Hayes Smartmodem) Which run around 300-1200 baud.

I bought this product so I could download info from the internet to my car diagnostic device. I looked at a lot of them but only Tripp Lite 19HS fit the bill. When I received it I plugged right to my computer and it did the job.

Only one that is Dependable.

By

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I have used this product for over 8 years. They are the only ones that will always work no matter what platform you are on. Other usb-serial adapter are hit or miss as to functionality on different computers and system. This is the only one that I have found that the hardware and software are from the same people. This is the only ones that I would and do recommend.

AV Industry must have

By

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

A lot of legacy and even current AV equipment still uses serial cable communication. I have a MacBook Pro running Yosemite, with Windows 8.1 running in Parallels. MOST of the AV configuration software is Windows only. This device allows my Virtual Windows PC to talk to an external serial device with this adaptor as if it were all native on it's own machine. Fantastic!

FANTASTIC

By 

from Undisclosed

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I've used this for years to allow older serial based equipment to work with newer hardware and it's been perfect. Currently using it with a Mutoh SC-650 as it was easier than finding a laptop with a DB9 port. I'd have no hessitation is buying another as and when the situation requires it. Recently went to set-up a mac book to cut graphics and was surprised to find current mac support on such an old adapter as well. Nice that it's not been abandoned.

Works until it doesn't

By

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I was using my USA-19HS without incident all day to console into a Cisco 3650 switch. I moved it over to a Cisco 1131AG AP, consoled in, and it stopped sending keystrokes to the console. After a reset of the AP, it stopped sending console output. I thought it was a failed AP but it was the Keyspan adapter. Swapped console cables, swapped the USB pigtail, and now all I can do is throw the Keyspan in the trash. I have no idea what caused the adapter to fail, but I'm not inclined to give this item a second chance. It is far too expensive for what it does.

Good and Bad

By

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I have been using this with a vinyl cutting plotter and when it works, it is flawless. BUT the problem lies in the fact that it does not always work, many jobs are interrupted midway thru which is extremely irritating and gets expensive when cutting for a large job. No I would not recommend it.
