USB Network Gate for Linux 3.5.0 Released: October 16, 2014

– Red Hat Enterprise Linux Server 6.0 support. Required version of hcd.h is included in the module sources.
– eveusb.jar – native Java binding for, allowing to write applications in Java for the daemon management, without using JNI framework
– callback (reverse) connection can be created (connection with a client initiated from the server side). Available both for standard build and console utilities (eveusbc and eveusbsh).
– possibility to set traffic compression algorithm – best or fast, the latter being the default one. -Z,–compress key allows setting the default value at the daemon start.
‘daemon’ command has new subcommand (for console utilities eveusbc and eveusbsh):
daemon compress [best|fast] – get or set hint for traffic compression
– new major version of libeveusb:
1. API: class members signatures were changed:
*EveusbEventHandler::writeToDaemon(const std::string &buf) => writeToDaemon(const void *buf, size_t count)
* EveusbEventHandler::readFromDaemon(std::vector &buf) => readFromDaemon(void *buf, size_t count)
* EveusbEventHandler::readFromDaemon returns zero if connection is disabled from the remote side.
* EveusbController::onDataAvailable returns error code when underlying call readFromDaemon returns value less or equal to zero.
2. New members added. See header files for details.
class EveusbEventHandler
void onCompressionHint(bool size_or_speed);
class EveusbController
int getCompressionHint();
int setCompressionHint(bool size_or_speed);

– eveusbc, –timeout parameter became a floating point value, and is measured in seconds now.
– “service eveusb stop” command now works on SLES 11
– GUI: activity log is limited to 255 last messages

– eveusbsh miscellaneous fixes (process crashed if daemon stopped, etc.)
– gtk-update-icon-cache crash during package installation
– issue when USB bus was still displayed in the GUI even if it actually was removed (OTG cable)
– package installation failure if system language was not set to English (en_US)
– issue when the driver prevented a system from entering suspend mode (pm-suspend)
– module compilation on the latest kernels

USB Network Gate for Linux 3.0.0 Released: September 12, 2013

  • Update: The current version 3.0.x is incompatible with the previous ones. One cannot combine the old version of client with the new server and vice versa.

The kernel version is not important for the server, however the client requires the module which can be compiled on kernel 2.6.18 and higher.
  • Network latency issue fixed for USB Wi-Fi and network adapters
  • Adaptive network traffic compression implemented. “share” command of console utilities has new “compression” option.
  • New major version of libeveusb is now being used:

bool compression() const;
void setCompression(bool compr);

Members removed from Device:
Members renamed in Device:
sharedTo() => sharedWith()
setSharedTo() => setSharedWith()

USB Network Gate for Linux 2.0.0 Released: August 7, 2012

  • Update: new name of the product
  • Added: freerdp plugin. Makes possible the access to shared USB devices in remote desktop session:
