Lexar Echo ZX 32GB Backup Drive Model LEHZX32GBSBNA
  • Verified Owner
  • Owned For: 1 day to 1 week

1 out of 5 eggs High Manufacturing Defect Rate 04/01/2013

This review is from: Lexar Echo ZX 32GB Backup Drive Model LEHZX32GBSBNA

Pros: The form factor is really nice. I wanted a fast UFD in this form factor to leave in a diskless Laptop for running Linux. There are a few other UFDs in this form factor available, but either there isn't a mention of the performance specifications or they are just slow in comparison.

Cons: Very high manufacturing defect rate. I have read other reviews on other sites and it seems many people are encountering the same problem. Lexar is usually good (one of the first to make UFDs) which is why I initially purchased one, but they dropped the ball with this product.

Other Thoughts: The Lexar Echo ZX 32GB would not work right out of the package (same day it was received). It (the first one) was intermittently detected as a Removable Disk but was not accessible. The filesystem was listed as unknown and the capacity is shown as 0 bytes. A prompt is displayed to Insert Disk Media when attempting to access the assigned drive letter or when attempting to format it. Basically the UFD behaved like a Card Reader without a Memory Card inserted. Tested the Lexar Echo ZX 32GB on two Windows XP desktop PCs, a Linux PC and a Windows 7 laptop PC with the same results. I RMA'd the first one and the replacement had the same problem. I RMA'd the second one for a refund. It seems like these have a very high manufacturing defect rate. It's almost as if Lexar never put the flash memory or connected it properly in the UFD chassis. I read somewhare that some UFDs with this form factor actually have microSDHC memory cards inside. If this is the case, I think they forgot that part when they made them!

Rosewill RC-USB-PS2-BG 6
  • Verified Owner
  • Owned For: 1 day to 1 week

3 out of 5 eggs Correction to Previous Review 04/02/2011

This review is from: Rosewill RC-USB-PS2-BG 6" USB to Dual PS/2 Adapter Cable/Beige

Pros: It works with both KVM Switches I have (see my previous review) when booting the OS (both Mouse and Keyboard). This makes this Adapter usable most of the time.

Cons: Hangs some Dell PCs in BIOS Setup with and without using a KVM Switch. Some Dells don't hang, but the Keyboard is very sluggish on some in BIOS Setup (possibly due to Keyboard resets caused by the Adapter) when it does work. It has similar problems in Dell Diagnostics (GUI version). The PC either hangs or the Keyboard works but not the Mouse. This can be a pain when servicing a PC.

Other Thoughts: I previously stated in error that this Adapter has a Holtek Semiconductor Inc. chipset (Product ID: 04d9; Vendor ID: 048e). It was late and I wrote down the info for the wrong device (actually the attached Mouse). It actually has a GASIA/GreenAsia Inc. Chipset (Product ID: 0e8f; Vendor ID: 0020) (I confirmed by removing the other USB devices), so it is still not the stated Cypress Semiconductor chipset.

Rosewill RC-USB-PS2-BG 6

  • Owned For: less than 1 day

3 out of 5 eggs Description Error or Part Changed 04/01/2011

This review is from: Rosewill RC-USB-PS2-BG 6" USB to Dual PS/2 Adapter Cable/Beige

Pros: Works with a StarTech Starview SV411KA KVM (w/audio and AC Adapter) Switch and a IOGEAR GCS612A MiniView Micro PS/2 Audio KVM Switch (all from Newegg).
The OS doesn't matter as long as it supports USB Keyboards/Mice (DOS, BIOS Setup etc. don't and must use the BIOS USB support, which can be finicky), but I'll list what Ive used anyway: Windows XP, Vista, Windows 7, Linux (Ubuntu). Keep in mind that the OS has to finish detecting the Adapter before you can use the attached Mouse and Keyboard.

Cons: The description says it has a Cypress Semiconductor chipset, which is why I purchased this model since this is the best/most reliable chipset for these adapters I have found and they seem to work with KVM Switches (which is what I need, since PS/2 KVMs just work better than USB KVMs due to their emulation of Keyboard and Mouse when switching). I've read they also work with old Model M keyboards (haven't tested yet, but I own several) I checked the one I received, and it has a Holtek Semiconductor Inc. chipset (Product ID: 04d9; Vendor ID: 048e) instead of the stated Cypress. If Rosewill has changed the chipset for this model, please change it back to Cypress.. they work better.. and I need several soon!

This model is sluggish when using the keyboard in BIOS setup on some PCs (Legacy USB Enabled).

Other Thoughts: Thank you Rosewell for including the chipset information, but it looks like there is an error or your product has unfortunately changed. It's the chipset that matters most with these adapters, and most of them unfortunately don't state which they use. The majority also use another chipset that is known to have problems (I don't think I'm allowed to say which). This is one reason so many people are having issues with PS/2 to USB Adapters. They keep trying different brands/models, but they each have the same chipset that doesn't work well... Other common problems are that people are not using a Mouse that supports both a USB and PS/2 connection (not sure about Keyboards). When used with a KVM Switch, there are less issues if the switch has an AC Adapter for power rather than just bus powered. Using these adapters with a bus powered KVM can be finicky due to inadequate power.
I need to use it more to see if there are other issues with this specific Adapter before ordering more...
